PROCESS FOR PREPARING COMPACTED GRAINED SODIUM SILICATE

To prepare a compacted, granular sodium silicate having an SiO2/Na2O molar ratio of 1.7:1 to 4.1:1, sodium silicate having a median particle diameter of <500 mu m is first mixed with a material increasing its hardness before being converted into pressed granules having particle sizes of 0.1 to 5...
