Product Description
Under standard conditions, the analyzed and fired substance is placed into the alumina crucible or bowl before being inserted into analyzing or firing equipment for heating. The heating and cooling rates vary depending on equipment characteristics and product specifications. The alumina crucible material undergoes thermal expansion, making controlled heating and cooling essential to prevent cracking and extend service life.
Key Features
- Excellent thermal conductivity
- Superior high temperature strength
- Outstanding wear and erosion resistance
- Exceptional thermal shock resistance
- Strong corrosion resistance
- High oxidation resistance
- Resistant to deformation and cracking
