Product 1

HCID 26051Sodium orthosilicate

Procedure

1104 g of disodium hydrogenphosphate dihydrate 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%. 15 kg of the amorphous sodium silicate are heat-treated at 720° C. for 90 min in a muffle furnace (Nabertherm, model W1000/H). The chilled product (about 10 kg) is pulverized using a jaw crusher and a disk mill.
