What is Manganese powder

Submitted by News on Mon, 12/10/2018 - 03:27

Manganese powder is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and it exists in many minerals. As a free element, manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Supply Yttrium(III) fluoride

Submitted by News on Mon, 12/10/2018 - 03:24

Yttrium(III) fluoride is an inorganic chemical compound with the chemical formula YF3. It is not known naturally in 'pure' form. The fluoride minerals containing essential yttrium include tveitite-(Y) (Y,Na)6Ca6Ca6F42 and gagarinite-(Y) NaCaY(F,Cl)6. Sometimes mineral fluorite contains admixtures of yttrium.

Yttrium(III) fluoride can be used for the production of metallic yttrium, thin films, glasses and ceramics.

Applications of Zinc sulfide

Submitted by News on Mon, 12/10/2018 - 03:21

The first time the phosphorescence of ZnS was observed by the French chemist Théodore Sidot in 1866. His findings were presented by the renowned chemist A. E. Becquerel who was involved in the research on luminescence and phosphorescence.

ZnS was used by Ernest Rutherford and others in the early years of nuclear physics as a scintillation detector, because it emits light on excitation by x-rays or electron beam, making it useful for x-ray screens and cathode ray tubes. It also exhibits phosphorescence due to impurities on illumination with blue or ultraviolet light.

Characteristics of Hafnium wire

Submitted by News on Mon, 12/10/2018 - 03:19

Hafnium is a shiny, silvery, ductile metal that is corrosion-resistant and chemically similar to zirconium(due to its having the same number of valence electrons and being in the same group). The physical properties of hafnium metal samples are markedly affected by zirconium impurities, especially the nuclear properties, as these two elements are among the most difficult to separate because of their chemical similarity.

What is Zinc Powder

Submitted by News on Mon, 12/10/2018 - 03:13

Zinc or spelter (which may also refers to zinc alloys), is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in the Earth's crust and has five stable isotopes. The most exploited zinc ore is sphalerite, a zinc sulfide. The largest exploitable deposits are found in Australia, Asia, and the United States.

What is Nickel particle

Submitted by News on Mon, 12/10/2018 - 03:08

Nickel is a chemical element with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity, though larger colletions of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface.

News of Copper wire

Submitted by News on Mon, 12/10/2018 - 03:02

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; and its exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.

What is Tungsten trioxide

Submitted by News on Mon, 12/10/2018 - 02:51

Known as tungsten trioxide or tungstic anhydride, Tungsten trioxide (WO3) is a chemical compound containing oxygen and the transition metal tungsten. It is frequently used in industry to manufacture tungstates for x-ray screen phosphors, fireproofing fabrics and in gas sensors. Due to its rich yellow color, WO3 is also used as a pigment in ceramics and paints. 
Other names: Tungstic anhydride; Tungsten(VI) oxide; Tungstic oxide
CAS: 314-35-8
Molecular formula: WO3
Molecular Weight: 231.84 g/mol
