Cryolite for?Abrasive and grinding tools


Cryolite for Abrasive and grinding tools Cryolite for Abrasive and grinding tools Cryolite for Abrasive and grinding tools
Alias: Sodium hexafluoroaluminate; Sodium aluminum fluoride
Molecular formula: Na3AlF6
Grade: Industrial grade
Appearance: powder, sand
Applications: Electrolytic aluminum, abrasive and grinding tool, glass, enamel, ceramics, pesticides
CAS Number: 13775-53-6; 15096-52-3
Colors: white

Uses: Specially used in the high-end abrasive and grinding tool industry, metal flux industry, etc.
Physical and chemical properties: white crystalline powder. PH value between 3.5-8 (adjustable), particle size of 40-12000 mesh (150μm ~ 1μm), the proportion of 2.95-3.01g / cm3 , a melting point of 920 ℃, insoluble in anhydrous hydrogen fluoride, water-soluble
Features :
1. The main content (F, Al, Na) can reach 98.5% or more, and the impurity content is low.
2. The various indicators are stable, the particle size distribution is uniform, and the crystal surface is smooth and clean, which helps to better combine with the abrasive. 3. It can improve the grinding efficiency and grinding ratio of abrasive tools.
4. Improve the wear resistance of abrasive tools and extend the service life of abrasive tools.
5. It helps to better take away the grinding heat during the grinding process.
