Product Details
1. Product Performance
· High-temperature resistance
Capable of withstanding extremely high temperatures (typically above 1600°C), making it suitable for processes such as high-temperature melting, chemical reactions, or material sintering.
· Thermal shock stability
It can effectively resist cracking or damage caused by temperature changes during rapid heating or cooling.
· Thermal conductivity
It has excellent thermal conductivity, enabling uniform heat transfer and making it ideal for experiments or production processes that require precise temperature control.
