 Fine Ceramic Products
Fine ceramics are representative ecological materials. Because of their excellent mechanical, electromagnetic and thermal properties, fine ceramics are used frequently in machines and equipment for industrial use in such fields as environment, energy and automobiles. This contributes to the prevention of environmental pollution, conservation of resources and the prevention of climate change.

Home-Use Solid Oxide Fuel Cell (SOFC) Cell Stack
A residential-use fuel cell has two parts a power generation unit and a water heating unit that uses exhaust heat from the power generation unit. The fuel cell has high energy efficiency, and produces only extremely small amounts of the greenhouse gases CO2, nitrous oxides, sulfur oxides or other byproducts. Use of the fuel cell as an environment-friendly system is expected to increase.

Kyocera realized the world’s highest level power generation efficiency* by promoting the development of cells and cell stacks, which form the core of solid oxide fuel cells (SOFC) with high power generation efficiency, and using fine ceramics, which have excellent thermal resistance and durability, as cell materials.

Ceramic Filters
Excellent in thermal resistance, ceramic filters are used in emission gas treatment equipment such as those at large-scale waste incineration plants which optimize efficient use of exhaust heat energy. Compared with the service temperature range (150 to 200℃) of conventional bag filters, ceramic filters are capable of collecting dust at higher temperature ranges (300 to 900℃) to realize improved energy efficiency during the use of waste heat and the reuse of filters by washing.

Ceramic Glow Plugs and Stacked Piezoelectric Elements
Ceramic glow plugs help reduce production of hazardous substances in exhaust gas as they support start-up of diesel engines.

Piezoelectric stacks for fuel injectors use piezoelectric ceramics and help optimize combustion by precise control of the high-pressure injection of fuels and the volume of injection as components of fuel injectors.

Aluminum Foundry Components
Kyocera’s silicon nitride ceramic material features outstanding high-temperature strength, heat and thermal shock resistance as well as corrosion resistance. When used in molten aluminum smelting equipment for the production of automobile engines and aluminum wheels, silicon nitride extends the product life of components and reduces the risk of impurities entering molten metal. With such benefits, silicon nitride contributes to the reduction of waste and improves product quality. Photo: Aluminum foundry components

LED Ceramic Packages and Single-Crystal Sapphire Substrates
Since ceramic materials are capable of efficiently diffusing the heat generated by LEDs, they can maintain high longevity and reliability without compromising LED luminescence efficiency. Such features led to the realization of very bright LEDs.

Single-crystal sapphires are used as the base substrates of LEDs and the backlights of mobile phones and LCD TV sets.

The first oil crisis (1973) made Kyocera aware of the necessity of solar power generation technology as a future energy source and was the impetus for us to start R&D of solar cells in 1975. In 1982, Kyocera successfully mass-produced multicrystalline silicon solar cells, which are now the mainstream, ahead of any other competitor in the world and started sales of residential-use solar power generating systems in Japan in 1993 for the first time in this country.

Today, we promote expanded use of solar power energy as a provider of residential- and industrial-use solar power generating system in and out of Japan and a power producer engaged in operation of industrial-scale solar power plants.

 Energy Management System
Energy management visualizes energy consumption from electricity or gas and realizes efficient use of energy. Kyocera supports power saving and ecological lifestyles by realizing storage of electricity generated by solar power generation and optimized use of power. Kyocera aims self-sufficiency in terms of electricity by utilizing management systems that make effective and wasteless use of power. In addition, we are actively involved in demonstration projects of automed demand response (ADR) that adjusts the power supply and demand balance in an entire area or community to ensure stable use of power.

Kyocera contributes to a future energy environment that can prevent climate change, a major concern for all humankind, by realizing a management system capable of maximum use of renewable energy.

 Printing Devices
Amorphous silicon (a-Si) photoreceptor drum
Used in core parts of laser printers and multifunctional products, high-durability amorphous silicon (a-Si) photoreceptor drums contribute to elongation of the service life of the equipment, reduction of maintenance costs, and reduction of waste materials.

High-efficiency LED light
Kyocera supplies high-color rendering index (CRI) LED modules that reproduce light very similar to sunlight. Application of ceramics to the package realizes a life expectancy of 100,000 hours, about twice that of a resin package, thereby helping reduce waste. We also provide high-efficiency LED lights for various uses, including office lighting, high ceiling lighting in factories and warehouses, and illumination of signboards and plazas. We contribute to reduction of power consumption by promoting these products.

 Cutting Tools

Milling cutters are used in a variety of metal cutting processes. Featuring both reductions in cutting resistance and excellence in loss resistance, milling cutters contribute to the improvement of productivity through stable processing and elongation of service life.

Recycling of Used Cutting Tools and Tip Cases
Kyocera collects and recycles cutting tools and tip cases after use at users’ production sites. Kyocera is actively involved in the reduction of waste and effective utilization of resources by properly recycling collected tips and tip cases for relevant applications, such as material powder and RPF (refuse plastic fuel), slag used for roadbed material, and others.   Image: Ceramic Chip Product Recycling System

 Organic Material
Silver Sintering Paste
We are recently seeing reinforcement of lead control regulations. One such move is regulation of high melting point lead, which had been excluded from the EU’s ELV Directive*.

Kyocera used low-temperature sintering performance of silver nano particles and developed a new connecting material, silver sintering paste, as a replacement of lead solder. The new paste will contribute to reduction of environmental impacts by chemical substances as it is being applied to vehicular LED headlights and inverters.

Halogen-Free Material
Halogenated elements, such as chlorine, bromine, and others, may produce harmful substances such as dioxin when burned. Their use is controlled according to regulations for chemical substances all over the world, with Europe as a leader. Kyocera has developed a wide variety of halogen-free* materials that conform to such legal regulations and contribute to a reduction in the environmental burden caused by the use of chemical substances.

* Based on the standard values of the Japan Electronics Packaging and Circuits Association (JPCA).

Low-VOC Materials
VOC (volatile organic compounds) is the generic name for organic compounds which are highly volatile and turn into vapor in the atmosphere, including toluene, styrene, and many other substances. VOC is considered to be one of the causes of suspended particle matters and photochemical oxidant, which are suspected to affect human health. In the insulation varnish field, where varnish is used for insulation of motors, Kyocera has developed and markets styrene-free varnishes that reduce VOC generation to 1/50 or less that of conventional products, as well as greatly reduce odor.
