실험 절차

(Comparison) 1600 kg of water glass with an SiO2/Na2O ratio of 2.06 and an active substance content of 45.5% were admixed with 36.8 kg of sodium hydroxide solution (48% strength) and spray-dried in a spray tower from Kestner to give an amorphous sodium silicate having an active substance content of 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). A second batch is treated identically. The chilled materials (about 24 kg) are pulverized using a jaw crusher and a disk mill.
