Brief Description
Description : | Bittern and soda ash are reacted to make magnesium precursor. Aluminium sulphate and soda ash solutions are reacted to make aluminium precursor. These precursors are blended and subjected to hydrothermal treatment under optimized process conditions. The slurry is filtered, dried, pulverized and sieved to obtain pharmaceutical grade SHT. |
