- Scope
- This standard specifies the method for determining the specific surface area of alumina or silica raw materials used in the manufacture of ceramics. Note (1): This method is a general determination method and can be applied to common commercial nitrogen adsorption devices of Renge. However, the degassing procedure needs to be strictly controlled. The calculation method is based on the BET (Brunauer Emmett Teller) equation. Note: This standard may involve hazardous materials, operations and equipment. This mark
