Sodium Fluoroaluminate/Sodium Aluminium Fluoride

Sodium Fluoroaluminate a. A large manufacturer in China b.have powder/granule/sandy-size three product lines

Sodium Fluoroaluminate/Sodium Aluminium Fluoride

 

Properties:

The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95—3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at 18—100°C. It’s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Uses: synthetic cryolite mainly used as the flux in the electrolytic aluminum and the fillers of rubber , grinding wheel , the milk whiter agent of enamel glass - shaded and the flux of the non - iron metal , etc . its merits are adjustable molecular ratio , lower cost and good fluidityPacking: In plastic coating woven bags with plastic film and paper bags inside, 25kgs, 50kgs or 1000kgs net each, or as the requirement of clients. 4. Specifications: GB/T4291-2007
