Material Recommendations

Primary Choice (SSiC): For high-temperature applications (>1380°C) requiring superior corrosion resistance, mechanical strength, and thermal shock resistance. Perfect for lithium battery materials and advanced ceramics.

Cost-Effective Alternative (RB-SiC): For applications under 1380°C where cost is a primary driver.

Alumina (Al₂O₃): Suitable for very high temperatures (up to 1800°C) in stable, non-thermal-shock environments.
