Why choose recrystallized SiC over other materials?

Recrystallized silicon carbide handles extreme heat better than most ceramics. It stays stable up to 1650°C in air and even higher in inert atmospheres. It also resists thermal shock, chemical corrosion, and wear. These features make it ideal for demanding industrial processes.

What industries use these crucibles?

They are widely used in metallurgy, foundries, and laboratories. Common applications include melting non-ferrous metals like aluminum, copper, and zinc. They are also used in research settings where purity and temperature control matter.

How long does a recrystallized SiC crucible last?

Lifespan depends on operating conditions. With proper handling and correct temperature control, it can last many cycles. Avoid sudden temperature changes and mechanical impacts to extend its use.

Can these crucibles be reused?

Yes. After cleaning off residues and checking for cracks or damage, they can be reused safely. Always inspect before each use. If the surface shows deep erosion or structural weakness, replace it to avoid failure during operation.
