Frequently Asked Questions (FAQs)

What is a silicon carbide crucible used for?

YICHOU silicon carbide crucibles are used in high-temperature metal melting, semiconductor crystal growth, and advanced material processing due to their heat resistance and chemical stability.

Is silicon carbide safe to handle?

Yes, solid silicon carbide is safe to touch, but powdered SiC can be abrasive—wear gloves when handling raw materials.

Why are silicon carbide crucibles expensive?

High-purity SiC requires advanced manufacturing processes, but its long lifespan and superior performance justify the cost compared to graphite or quartz alternatives.

What is the maximum temperature a silicon carbide crucible can withstand?

Our crucibles can operate continuously at 1600°C (2912°F), with short-term tolerance up to 1800°C (3272°F) in inert atmospheres.

How does silicon carbide compare to graphite crucibles?

Longer lifespan (3-5x more durable than graphite)
Better oxidation resistance (graphite degrades in air at high temps)
Higher thermal conductivity for more uniform heating

What is the difference between green and black silicon carbide?

Black SiC: More economical, used for general industrial applications
Green SiC: Higher purity (99.5%+), used for precision grinding and semiconductor processes

Can silicon carbide crucibles be used for melting iron?

Yes, but for prolonged iron melting, we recommend our special reinforced SiC crucibles to prevent iron carbide formation.
