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.

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.
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
Molecular formula: WO3
Molecular Weight: 231.84 g/mol
Barium fluoride is a chemical compound of barium and fluorine. Molecular formula: BaF2. The highest quality Barium Fluoride also has application as the fastest known scintillator material and is used in High Energy Physics Experiments. Barium Fluoride (BaF2) is commonly used as a scintillator material and is useful as a transmission window material for IR spectroscopy particularly for analysis of fuel oil samples. Molecular Weight: 175.34 g/mol.
Strontium fluoride, SrF2, also called strontium difluoride and strontium(II) fluoride, is a fluoride of strontium. Another proposal is that polarisation of the electron core of the strontium atom creates an approximately tetrahedral distribution of charge that interacts with the Sr-F bonds. It is a stable white brittle crystalline solid with melting point of 1477°C and boiling point 2460°C. Strontium Fluoride has only specialist applications.
Magnesium fluoride is an inorganic compound. Magnesium fluoride is transparent over an extremely wide range of wavelengths. Windows, lenses, and prisms made of this material which can be used over the entire range of wavelengths from 0.120 μm (vacuum ultraviolet) to 8.0 μm (infrared). MgF2 is also used as a flux.
Zinc oxide is an ingredient in many products, including certain creams and ointments used to prevent or treat minor skin burns and irritation. Zinc oxide overdose occurs when someone accidentally or intentionally eats this medication. In material science, ZnO is a wide-bandgap semiconductor of the II-VI semiconductor group (since zinc and oxygen belong to the 2nd and 6th groups of the periodic table, respectively). The native doping of the semiconductor (due to oxygen vacancies) is n-type.
Cerium fluoride is a new inorganic scintillator with a high density, short radiation and speedy decay. It is particularly suitable for high count rates, strong blocking ability and nanosecond time-resolved nuclear medicine imaging, high-energy physics and nuclear science in the trial.
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally going on oxide of titanium. When exploited since a pigment, it is called titanium white, Pigment White 6, or CI 77891. It is noteworthy for its full chain of coverings, from paint to sunscreen to food colourising, for which it was caved in E identification number E171.
Silicon dioxide, also known as silica, is an oxide of silicon that has been known for its hardness since antiquity. Silica is used primarily in the production of window glass, drinking glasses and bottled beverages. The majority of optical fibers for telecommunications are also made from silica. It is a primary raw material for many whiteware ceramics such as earthenware, stoneware and porcelain, as well as industrial Portland cement.
