Calcium alloy composite alloy is composed of the elements silicon, calcium and iron, is an ideal compound deoxidizer, desulfurizer. Been widely used in the production of high quality steel, low carbon steel, stainless steels and nickel base alloys, titanium based alloys and other special alloys; and suitable for the converter practicing steel plant warming agent; can also be cast iron inoculant additives and ductile iron production.
Earth permanent magnet points samarium cobalt (SmCo) permanent magnets and NdFeB (NdFeB) are the permanent magnets, which SmCo magnets, magnetic energy product of NdFeB permanent magnets. Energy product between 27-50 MGOe between the 15-30MGOeknown as the "permanent magnet" is the magnetic permanent magnet materials.
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.
Barium titanate is the inorganic compound with the chemical formula BaTiO3. Barium titanate is a white powder and transparent as larger crystals. This titanate is a ferroelectric ceramic material, with a photorefractive effect and piezoelectric properties.
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.
Cryolite (Na3AlF6, sodium hexafluoroaluminate) is an uncommon mineral identified with the once large deposit at Ivigtt on the west coast of Greenland, depleted by 1987.
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.
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.
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.
