Applicaton: Structural material in atomic reactor; spout of plane, rocket engine; High temperature solid lubricant and many kinds of parting Detail description: Hexagonal Boron Nitride Boron nitride is a white solid material in the as produced hot pressed form. It is a low porosity solid. It is easily machined into complex shapes using standard carbide tooling. The material is anisotropic in its electrical and mechanical properties due to the platy hexagonal crystals and their orientation during the hot press consolidation. Key Properties High thermal conductivity, Low thermal expansion, Good thermal shock resistance, High electrical resistance, Low dielectric constant and loss tangent, Microwave transparency, on toxic, Easily machined — non abrasive and lubricious, Chemically inert, Not wet by most molten metals. Use Structural material in atomic reactor, spout of plane, rocket engine, High temperature solid lubricant and many kinds of parting agent of precision molding products, High temperature resistant, anticorrosive boron nitride and boron nitride compound ceramics, Synthesize cubic boron nitride, Compression resistant and high temperature resistant lubricating grease, All kinds of high temperature resistant, anticorrosion coating, Insulator for high pressure high frequency electricity and plasma arc, Ox dating additive for refractory materials.

Synthetic Cryolite/Sodium Aluminum Fluoride /Cryolite Bath/ Sodium Cryolite Cas NO.: 13775-53-6 Appearance : white crystalline powder or a sandy-size granularity Packaging : In 25kg/50kg plastic woven bag lined with high pressure polyethylene plastic bag Minimum Order : 20ton Shipping Port : TIANJIN Product's Description Cas NO.: 13775-53-6 Appearance : white crystalline powder or a sandy-size granularity Packaging : In 25kg/50kg plastic woven bag lined with high pressure polyethylene plastic bag Minimum Order : 20ton Shipping Port : TIANJIN Introduction: physical characteristics: 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¡ª3.01g/cm3, melting point about 1000 centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. 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 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively. The size distribution can be sandy (80mesh), powder (200mesh, 325mesh), granular (0-10mm). Other items can be specified according to special requirement. Specification: Molecular FormulaNa3AlF6 Molecular Weight 209.94 Properties It is a colorless monoclinic crystal, but often appears off-white, pompadour, straw yellow or black due to impurities. It has relative density of 2.9-3.0, mp 1000. It is slightly soluble in water, and its aqueous is acidic. It decomposes to release poisonous HF gas while meeting sulfuric acid. UsagesIts mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for resin and rubber-boned abrasive wheels.
