Silicon Carbide

Silicon carbide, mainly consisting of SiC, is the most corrosion-resistant ceramic, used in mechanical seals and pump parts. It maintains its strength up to 1400°C.

Features

  • Silicon carbide maintains its strength even at temperatures up to 1400°C.
  • Notable features of this material are extremely high thermal conductivity and electrical semiconductivity.
  • Silicon nitride has high hardness and corrosion reisistance due to its chemical and physical stability.

Configuration

Dimensional precision achieved by machining

When dimensional precision is required for machined ceramics, Kyocera is capable of achieving the tolerances as shown in the table below. If greater tolerances are required, please consult us.

■PRECISION MACHINED PRODUCTS

Ultra-precision is possible with Kyocera's unique techniques.
Precision machining is affected by shape and material.
Some practical examples are shown in the table below.
