Product Description

Supply 98% cryolite synthetic cryolite, 7681-49-4,aluminum sodium fluoride

 

Physical properties: colorless triclinic crystals. White powder or orthorhombic great six-sided crystals. Density 3.00g / cm3. Melting point 1040 ℃. Boiling Point (sublimation) 1272 ℃. There are several hydrates exist; slightly soluble in water, soluble in hot water. Difficult to dissolve in acid and alkali solution, insoluble in most organic solvents. It can be heated to 300-400 ℃ steam partial decomposition of hydrogen fluoride and alumina. There are three hydrates, namely monohydrate, trihydrate and nine water thereof.

 

Application :

1. Used as pesticide in agriculture .

2. Used as bactericide in brewing industry .

3. Used as wood preservative , pharmaceutical preservative .

4. Used as welding flux .

5. Used as alkaline zincate galvanized additive .

6. Used in papermaking and ceramic industry .

7. Used as phosphate coating windustry accelerator, resulting a stable phosphate solution , phosphate refinement , improved phosphate coating performance .

(Aluminum and its alloys phosphate in great danger of closure with negative catalytic Al3 + .)
