Fluorosilicic acid

CAS: 16961-83-4
Molecular Formula: H2SiF6
Molecular Weight: 144.09
Product description:1. Used for determination of barium. Separation of barium and strontium. The electrolysis of lead and tin refining. The preparation of fluorosilicate. Disinfection equipment. Is preparing fluorine sodium silicate, potassium, ammonium, magnesium, copper, barium, lead, and other fluorosilicate, and the basic raw material of silicon tetrafluoride. Used in metal plating, wood preservation, disinfection, beer brewing industry equipment disinfection H2SiF6 (1% ~ 1%) and the electrolytic refining of lead, etc. Also used as a mordant and metal surface treatment agent. (2) fluosilicate also used in some electroplating additives, fluosilicic acid or salts used in chrome plated to add, but with sulfuric acid root has a similar effect, and can improve the efficiency of current to about 20%, brightness, light current density range is widened; Fluosilicic acid activation, the chromium plating layer power outage time is short, to continue after plating, binding force is almost unaffected, so in the barrel plating chromium fluosilicate is necessary to add ingredients; Fluosilicic acid can reduce the current density of chromium plating, plating coverage, but increase the corrosive solution. 3. Making fluorosilicate and original silicon tetrafluoride.
