Selenium hexafluoride is the actinic admixture of blueprint SeF6. It is a colourless gas. It can be able from the elements or by the acknowledgment of bromine trifluoride, BrF3 and selenium dioxide. It is agnate to sulfur hexafluoride, as it is octahedral (Se-F band breadth 168.8pm) and beneath accustomed altitude is apathetic to water.The gas can be anesthetized through 10% NaOH or KOH after change.
Selenium hexafluoride are toxic, even at low concentrations, will still affect the animal body. Selenium hexafluoride gas is corrosive, astringent affliction of the skin, eyes and close membranes. Inhalation can could could could cause adversity breath and pulmonary edema. Acquaintance with derma or eye affliction and tearing, can could could could cause actinic burns, abiding tissue damage, even blindness. The aqueous acquaintance hexafluoride selenium may could could could cause burns or frostbite. The U.S. Occupational Safety and Health Administration and the U.S. anchored for the affair of Governmental Industrial Hygienists hexafluoride selenium in best air absorption accepted is 0.05ppm.
Selenium in the electronics industry can be acclimated as a photoelectric cell, solar cell, in TV and radio fax application selenium. Selenium bottle appearance or acerbic can arresting superior lens bottle absolute 2% selenium, selenium collapsed bottle for solar calefaction alteration bowl and laser window bittersweet filter.

Antimony pentafluoride structure
Antimony pentafluoride is the actinic admixture with the blueprint SbF5. This colourless, adhesive aqueous is a admired Lewis acerbic and a basic of the superacid fluoroantimonic acid, the arch accepted acid. Some appearance that accord the admixture accurate absorption are its Lewis acidity and that it aswell reacts with about all accepted compounds.
Antimony pentafluoride is accepted except fluoride seven gold (AuF5.F2) alfresco the arch Lewis acerbic fluoride acid, six antimony ( autograph HSbF6 or HF.SbF5 ) is accepted to a lot of of the cool acid,, in the aerial state, SbF5 yield D3h agreement group, as a trigonal bipyramidal agreement (Figure ). In the aqueous and solid anatomy of added complex. A aqueous absolute polymer, and anniversary Sb is the apparent of the physique eight, the blueprint for [SbF4 (μ -F ) 2]n. In the apparent accompaniment as four dimer, namely, actinic blueprint [SbF4 (μ -F ) ]4. In the dimerization of four eight yuan in the Sb4F4 ring Sb-F band breadth is 2.02 ? four Sb; for the added and affiliated to the F ?ligand, its Sb-F band beneath 1.82 ?. [2] congeners of PF5 and AsF5 in aqueous and solid are monomer, apparently because of the axial atom has the advantages of baby volume, bound the allocation number. BiF5 aggregation.

The use of mixed refrigerant R404A
Mixed refrigerant R404A under normal temperature and pressure, R404A is a affectionate of non-azeotrope fluoro-alkane refrigerant chargeless of chlorine, and a achromatic gas.It is stored in a butt by aeroembolism and abounding gas.It doesn't abort atmosphere blast because ODP is zero. R404A is a chlorinated non azeotropic admixture refrigerant beneath accustomed temperature, is a achromatic gas, accumulator the butt is aeroembolism abounding gas. The ODP is 0, R404A is accordingly does not abort the blast band ecology aegis refrigerant. Main uses: mainly acclimated as a acting for R22 and R404A R502, has the advantages of cleanness, low toxicity, no burning, acceptable cooling aftereffect and added characteristics, are broadly acclimated in low temperature algidity system.
Mixed refrigerant R404A is a affectionate of refrigerant of surroundings-protection model, acclimated in replacing R22 & R502.It has a acceptable attributes of cleaning, low poison, non- combustion, good-refrigeration and so on, and abundantly acclimated in air-conditioner.It is achromatic and cellophane liquid.

The use of ammonium fluorosilicate
Ammonium fluorosilicate is a white apparent powder, acrid in booze or water, but baffling in acetone.
Used for the brewing industry, disinfectant, bottle carving agent, bolt moth agent, copse preservative, but aswell for the ablaze metal casting, plating, and is aswell acclimated by the greensand extracting potassium and alertness of constructed cryolite and ammonium perchlorate. Determination of barium alkali is aswell acclimated in actinic analysis. Fluorescent powder, silica sand, and sulfuric acid, again ammonia and.
Ammonium fluorosilicate non-flammable, toxic, with a able irritant. React with acids to afford baneful acerb flue gas. Heat appear by the atomization of the baneful gas. Wrongly or inhalation. Able aesthetic aftereffect on the eyes, skin, close membranes and high respiratory tract. Assimilation can could cause throat, bronchial spasm, inflammation, actinic pneumonitis, pulmonary edema. Handling Precautions: bankrupt operation, accommodate able bounded ventilation. Prevent dust appear into the air workshop. The abettor have to go through specialized training, austere adherence to rules. Proposed operators abrasion a dust affectation (full cover), 52,400 to abrasion careful clothing, elastic gloves. Avoid dust.
