Introduction to aluminum silicate characteristics
Aluminosilicate: It is produced by using hard clay clinker as raw material, melting or blowing into fiber by electric resistance or electric arc furnace.
Characteristics: Low thermal conductivity Excellent thermal stability and chemical stability without binders and corrosive substances.
Aluminium silicate application: the interlayer filling of the equipment, the fiber castable, and the raw material of the coated raw material vacuum forming product.
Aluminum silicate is an aluminosilicate.
Traits: colorless crystals.
Chemical formula: Al2(SiO3)3
Relative molecular mass: 282.23
CAS No.: 12141-46-7 [1]
Solution: Do not melt in water.
Uses: Used in glass, ceramics, and as paint pigments and fillers for paints, rubber and plastics.
Preparation or source: present in the soil. Alumina and silica can be mixed in a ratio and then sintered.
Remarks: The ratio of alumina to silica is not constant, 1:1 aluminum silicate, density 3.247, melting point 1545 ° C (decomposition). 1:3 silica, density 3.156, melting point 1920 ° C.
Category: Inorganic salts
Application: Aluminum silicate is mainly used to make high temperature resistant fireproof insulation cotton, board, pipe, seam felt, fire insulation cloth, high temperature resistant paper, fire resistant insulation rope, belt, fire insulation needle acupuncture blanket (with silk, spray Blow), brick. Inorganic fireproof decorative board. Inorganic fire shutters, etc.
