Chromium Powder forms an essential product category with various industrial applications. Composed of finely milled chromium particles, this powder offers unique properties, including high corrosion resistance, excellent hardness, and thermal stability. Widely used in metallurgy, coatings, and welding industries, Chromium Powder plays a crucial role in producing wear-resistant alloys, protective coatings, and high-temperature materials. Its ability to enhance the performance and durability of products makes it a sought-after material in aerospace, automotive, and manufacturing sectors. As a dependable choice for specialized applications, Chromium Powder empowers industries to achieve superior results, ensuring reliable and efficient solutions for diverse challenges.
Nano chromium powder has high purity, uniform particle size, complete surface structure, easy dispersion, large specific surface area and high surface activity. Due to its high surface activity and excellent electrical conductivity, nano-chromium powder is widely used in semiconductors, conductive coatings, chemical catalysts and solar energy absorbers. Refining superalloys, high-performance alloys, and precision alloys as chromium element additives.
Chromium is used to make stainless steel, auto parts, tools, magnetic tapes and video tapes, etc. Chromium plating on metal can prevent rust, also known as Kadomi, which is sturdy and beautiful.
Chromium can be used to make stainless steel. The color of red and emerald also comes from chrome. As the most important metal in modern technology, chromium-nickel steels fused in different percentages are incredibly varied and varied.
The industrially used chromium ore is chromite, which belongs to spinel (MgO·Al2O3) and magnetite (FeO·Fe2O3), and its general chemical formula is (Fe, Mg)O·(Cr, Fe, Al2O3). Due to the mutual replacement of divalent elements (Mg2+, Fe2+, Zn2+) and trivalent elements (Al3+, Fe3+, Cr3+), various ores of different compositions can appear. In addition to the main components FeO and Cr2O3, it generally contains MgO, Al2O3 and other impurities of different components. The structure and composition of the ore have a significant impact on the use. For example, chrome spinel is more difficult to reduce than chromite (FeO Cr2O3); for chrome ore containing serpentine, if the volatile content is greater than 2%, the chrome refractory bricks made of it are used. When heated to 1000 ºC, it will burst due to the release of crystal water. The United States consumed 917,000 tons of chromite in 1978, and its uses are distributed as follows: 61% for metallurgy, 21% for chemical industry, and 18% for refractory materials. In 1981, the price of chrome ore in the London market: Turkey ore (48% Cr2O3, Cr/Fe=3) 130-135 US dollars / ton, South Africa (Azania), chrome ore (44% Cr2O3) 60-70 US dollars / ton.
