Product Details
1. Production process
Raw material: high-purity alumina powder—molded in custom molds—produced into semi-finished products—sintered at a high temperature of 1600℃—finished product
2. 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.
· Surface treatment
The surface has undergone special treatment (such as a hemp-like texture), with a coarse-grained outer surface and a smooth inner surface (the outer layer is breathable, while the inner layer is dense).
