Water → Sodium orthosilicate

Participants

Reaction Steps

treating the waterglass solution in a spray-drying zone with hot air at 200° to 300° C. for a residence time of 10 to 25 seconds and at a temperature of the exit gas leaving the spray-drying zone of 90° to 130° C., to form a pulverulent amorphous sodium silicate having a water content (determined as the loss of ignition at 700° C.) of 15 to 23% by weight and a bulk density of more than 300 g/l,
