Versuchsvorschrift

50 kg of water glass having an SiO2/Na2O ratio of 2.06 and an active substance content of 45.5% were admixed with 0.404 kg of sodium hydroxide solution (48% strength) and spray-dried in a laboratory spray dryer (spray tower) from Anhydro to give an amorphous sodium silicate with an active substance content of 84%. 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 material (about 10 kg) is pulverized using a jaw crusher and a disk mill.
