Product 1

HCID 26051Sodium orthosilicate

Procedure

1104 g of disodium hydrogenphosphate dihydrate and 683 g of anhydrous soda are dissolved in 50 kg of water glass having the composition as in Example 1, and the solution is spray-dried in a laboratory spray dryer (spray tower) from Anhydro to give an amorphous sodium silicate having an active substance content of about 83%.
