Title: Maunfacture of sodium silicate
Inventor: IWAMOTO TOYOZOU
IPC: C01B33/32
Filed: 1978-07-17
Abstract: PURPOSE: To obtain uncolored sodium silicate with high filterability by previously heat treating clay as raw material for silicic acid at a high temp. above a prescribed temp.  
     CONSTITUTION: Clay as raw material for silicic acid is heat treated in a rotary kiln or a fluidized bed at above 300, pref. 430W550°C for several minW6 hr and further heat treated under press. in an autoclave together with an aq. soln. of caustic soda to obtain sodium silicate. As compared to a product manufactured using untreated clay the resulting aq. soln. has high filterability and a slightly colored product is obtd. This reason is supposed to be caused by subliming sulfur in clay through heat treatment to avoid formation of sulfide colloid by reaction of sulfur and metal such as iron, nickel or manganese, and by eliminating bad influence of the colloid on filterability and coloration.
