Cryolite Powder LR 500 gr

SKU : O-5285.0500
CAS : 15096-52-3
Formula : Na3AlF6
Grade : Laboratory Reagent
Primary Laboratory & Research Uses :
  • Metallurgical Research: Used as a flux to lower the melting point of aluminum oxide (alumina) from over  to approximately during experimental electrolytic extraction studies.
  • Model Compound Studies: High-purity cryolite serves as a stable reference material for high-temperature studies of molten salt systems and ionic conductivity.
  • Chemical Synthesis: Acts as a reagent or intermediate in producing other fluoride-containing chemicals, such as sodium or aluminum fluoride, and specialty catalysts for alkene polymerization.
While the LR grade is typically for labs, the compound’s broader industrial uses include:
  • Glass and Ceramics: Functions as a powerful opacifier to create “milky” white or opalescent glass and enamel. It also reduces the melting temperature of silica to save energy.
  • Abrasives: Used as an active filler in resin-bonded grinding wheels to improve cutting efficiency, reduce friction, and extend the lifespan of the tool.
  • Pyrotechnics: Added to fireworks to produce a vibrant yellow color.
  • Metal Surface Treatment: Included in pickling pastes for stainless steel and used as a flux in welding and soldering to remove oxides.
  • Pesticides: Historically used as a relatively safe insecticide for fruits and vegetables, though this use has declined due to environmental concerns

Hello
Can we help you?
Labotiq focuses on a practical and precise field: laboratory supplies, chemical reagents, equipment, and plastic labware. This kind of work is all about accuracy, safety, and trust, because even small details can affect the final result. The same idea is becoming more relevant in digital entertainment, where choosing a platform also means paying attention to reliability, transparency, and user protection.Online entertainment has turned into an everyday habit, from streaming and mobile games to casino-style platforms and interactive services. Still, a good digital experience starts with clear rules, secure payments, licensed operators, and easy-to-understand information. Anyone interested in safe online leisure and the Spanish gambling market can find a useful reference in mejores casinos en España. The topic is not only about fun, but also about choosing platforms carefully, understanding how regulation works, and avoiding random decisions when money and personal data are involved.That creates a simple connection between the two areas. Labotiq supports laboratories with dependable products for controlled work, while trusted information about digital entertainment helps users feel more confident online. When reliability comes first, both laboratory processes and online services become easier to understand, safer to use, and more valuable in everyday life.
