Fine Ceramics, sometimes referred to as "advanced ceramics," are engineered materials that support the development of cutting-edge technology.

Fine Ceramics Use Highly Purified Raw Materials

Raw Materials Need to Meet Demanding Performance Requirements

Inorganic solid powders are converted into products with extreme density and hardness.

Fine ceramics are made from inorganic solid powders with precisely controlled properties of purity, particle size and particle distribution. The process involves mixing different powders together to produce a ceramic with specific material characteristics. This powdered mixture is blended with a binder so it can be molded to precise specifications, machined in a "raw" state, and then fired in a controlled furnace.
Firing, also called sintering, involves heating the raw ceramic to a temperature below the melting point. This eliminates the moisture and binder, shrinking the microscopic gaps between particles and fusing them together to form fine ceramic products of extreme hardness and density.
