AMORPHOUS ALKALI METAL SILICATE, PROCESS AND USES |
摘要 |
A particulate amorphous alkali metal silicate is prepared by heating a mixture of silicate glass and water or aqueous solution to a temperature of about 300 to 400 DEG C to provide a foamed material that is easily formed into particles of less that about 20 microns. After careful hydration, a product having 0.5 to 15 % water based on loss of ignition (LOI) of product at 800 DEG C is produced that controls the activity of magnesium in solution and is, therefore, a useful detergent ingredient.
