Tricobalt tetraoxide chemical formula Co3O4. Similar to ferric oxide, it can be regarded as a compound of cobalt oxide and high cobalt oxide. It is black or gray-black powder. Water is easily absorbed in exposed air, but no hydrate is formed. It is soluble in nitric acid. When heated above 1200℃, it will decompose into cobalt oxide.
Titanium powder is a silver-gray irregular powder with a large inspiratory
capacity and is flammable under high temperature or electric spark conditions.
Titanium silicide is used in the semiconductor industry. It is typically grown by means of salicide technology over silicon and polysilicon lines to reduce the sheet resistance of local transistors connections. In the microelectronic industry it is typically used in the C54 phase.
Titanium nitride has a typical NaCl-type structure and belongs to face-centered cubic lattice with lattice constant a=0.4241 nm. TiN atoms are located at the corner top of face-centered cubic lattice.
Nano-titanium dioxide is a white loose powder with strong UV shielding effect, good dispersion and weather resistance. It can be used in cosmetics, functional fibers, plastics, coatings, paints and other fields, as ultraviolet shielding agent, to prevent ultraviolet damage. It can also be used in high-grade automotive topcoat with angular heterochromic effect.
Stainless steel powder is in the shape of particles. It has good corrosion resistance and durability. Its flaky particles can be positioned parallel to the surface of the coating film and distributed throughout the coating film to form a shielding layer with excellent hiding power to block moisture.
Aluminum powder has silver-white metallic luster, so it is commonly known as ALUMINIUM-SILVER powder or silver powder. Its chemical composition is actually "aluminium", not "silver".
Aluminum powder is mainly used in powder coatings, inks, plastic masterbatches, printing, imitation gold paper, imitation gold cards, gold film, textiles, but in water-based paints and paints with acid and alkali, it will be oxidized and blackened. It is not recommended for applications requiring acid and alkali resistance and combination with rainwater.
Iron-silicon-aluminum alloy is an alloy powder of 85% iron, 9% silicon and 6% aluminum. It is processed into a ring or E-type magnetic powder core by special process. It is commonly called Kool Mμ magnetic powder core or Sendust magnetic powder core. .
Ruthenium trichloride is a chemical substance and its molecular formula is RuCl3. It is a lustrous crystal grain, generally grayish brown or dark red, corrosive and highly deliquescent. Used in heterogeneous catalysis or homogeneous catalysis, electroplating, electrolytic anodes, electronics industry and other important chemical raw materials.
