Low Na2O Tabular Alumina 3-6mm

Low Na2O Tabular Alumina 3-6mm is an inert particle with high aluminum oxide purity min 99.5%. The sodium content is less than 0.1%.  It gets better themal performance than normal sodium ones. The low sodium leads to higher Al2O3 purity, higher bending strenght and higher chemical resistance. It works on furnace building, casting filter,etc.

Properties:

1. Low sodium content (not higher than 0.1%)
2. High purity, aluminum oxide content is not less than 99.5%
3. Large crystal particles, high crystal strength
4. Bulk density is higher than ordinary sintered aluminum oxide
5. Significant low porosity 
6. Low water absorption
7. Good thermal shock resistance
8. Low thermal conductivity, good insulation performance
9. High toughness

Applications:

Refractory products made of low-sodium tabular aluminum oxide have good corrosion resistance, erosion resistance, thermal shock resistance, peeling resistance, etc., and are suitable for various fields in the refractory industry. In addition, it is also widely used in high temperature industries such as metallurgy, industrial ceramics, thermal conductive materials, and building materials.
