Silicon Carbide
One of IPS Ceramics’ most popular product groups is our Silicon Carbide range. These products are used for heat treatment applications involving temperatures or weights that would not be suitable for our Cordierite Kiln Furniture products; or in applications designed to reduce mass, save on energy consumption, and increase output compared to previous setups. Silicon Carbide is used by a wide array of industries, including tableware, sanitaryware, metallurgy, aerospace, power generation, and many more.
Silicon Carbide has:
- Excellent load-bearing ability
- Good thermal shock resistance
- Extreme hardness and abrasion resistance
- Low density while still exhibiting high mechanical strength.
- High chemical stability
- Allows for energy saving and increased capacity
- Retains all of these properties even in high temperatures and aggressive environments.
These properties make it the material of choice for load-bearing applications in the range 1110ºC to 1650ºC (2012ºC to 3000ºF).
