Frequently Asked Questions

What is the difference between RSiC and NSiC?

Recrystallized Silicon Carbide (RSiC) is made by high-temperature sintering without additives, offering high purity and excellent thermal conductivity. Nitride Bonded SiC (NSiC) uses silicon nitride as a binder, providing good strength and oxidation resistance at lower cost.

Can you manufacture custom-shaped components?

Yes, we specialize in custom fabrication. Provide your drawings or specifications, and we will produce tailored ceramic parts to meet your exact requirements.

What industries use your ceramic products?

Our products are used in metallurgy, ceramics firing, glass manufacturing, semiconductor processing, chemical reactors, and high-temperature furnace systems.

Do you offer international shipping?

Yes, we ship globally with reliable logistics partners. Lead times and costs depend on destination and order size.
