Overview
The instrument is designed for HV substations and power plants to test the characteristic of large HV transformer, electric machines and appliances, remote power cable or buried cable and other electrical insulation resistance in strong interference environment. It also can be widely used for testing characteristics of insulation resistance in other area.

Commodity: Synthetic Cryolite Formula: Na3AlF6 M.W.: 209.95 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.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its 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. Specifications: Appearance white powder F 52% min Al 12% min Na 33% max SiO2 0.36% max Fe2O3 0.08% max CaO 0.5% max P2O5 0.03% max SO4 0.6% max H2O 0.4% max Loss on ignition 2 % max Uses: Its 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. Packing & Storage: In plastic coating woven bags with plastic film inside, 25kg,40kgs, 50kgs or 1000kgs net each, or as the requirement of clients.Stored: in a cool , ventilated, dry place.

We are supplier and exporter of Hematite Powder. Hematite Powder is a mineral, coloured black to steel. It is mined as a main of iron ore and used as a weighting agent in oil drilling. It is the mineral form of iron(III) oxide (Fe2O3). Fluids weighted with API Hematite Powder contain fewer solids by volume than, making higher mud fluids possible. API Grade Hematite Powder is applicable in all types of drilling fluids, including freshwater, seawater and oil-base muds. It is used as a density increasing product, used as a weighting agent and in the paint industry. Hematite is also a harder mineral than Barite so it is more resistant to particle size degradation. High Density Hematite Powder API Grade -SG = 5.19 - 5.47 -Fe2O3 = 96.70% -Fe = 71.82% -SiO2 = 0.89% -Mesh Size (passing at 98%) = 325
