Nickel has a high chemical stability. No rust even it is heated at 700-800 ℃ ID. Nickel powder with high resistance to corrosion for a variety of organic materials, such as fluorine, alkali metals and brine. Passivation of the surface and maintain the resistance to corrosion in concentrated nitric acid. Has a slow response in dilute hydrochloric acid, sulfuric acid and nitric acid. Magnetic metals, nickel presents a good mechanical strength and durability. They are able to resist all types of treatment.
Alloys of nickel and pure nickel powder with a wide range of uses in the economy. Nickel good performance of polishing purity nickel powder is used in coating technology nickel. Emphasizes pure powder of nickel in radar, television technology, the nuclear industry, the pilot and other modern applications. The missiles, alloys, nickel or nickel powder for high temperature materials. Nickel powder in the powder metallurgy production of a variety of materials, nickel, are widely used as catalysts in the chemical industry. The compounds of powder metallurgy of nickel in the production of alkaline batteries, nickel sulfate is typically used for electrolytic nickel plating, formic acid, nickel for the hydrogenation of oils, nickel hydroxide prepared in the production of alkali metal nitrate, nickel tested ceramic brown pigment. However, the salts of nickel metal and nickel is pure modern industrial purposes, in particular through the alloy.
With the increasing demand of the reform and opening of China, the rapid development of industrial engineering, electrical engineering, mechanical engineering, chemical and other nickel powder. In conclusion, the use of nickel powder can be classified into six categories. Metallic materials, which include the production of stainless steel, heat resistant steel, and various alloys such as 3000, which may be more than 70% of the consumption of nickel, nickel-metal material are typical – alloys, chromium, nickel – cobalt chromium molybdenum , chromium, nickel, copper, nickel, titanium, nickel and shape memory and storing hydrogen.
The powder used in the nickel plating, and its use is approximately 15% of the consumption of the metal powder. This is mainly. Steel and other metallic materials in the backing layer of the surface layer of durable, resistant to corrosion, the corrosion resistance of the equipment used galvanized 15% to 20% of nickel powder as a hydrogenation catalyst in the oil industry. The catalyst is dispersed nickel on alumina composite. This catalyst is not easy to be poisoned by H2S, SO2. Nickel powder can be used as chemical energy and material for the manufacture of batteries. The industrial production of Ni-Cd and Ni-Fe, Ni-Zn and Ni-H2 battery waterproof. Also it can be used for the production of dyes and pigments. Furthermore, the formation of a yellow-orange pigment, pigment TiO2, NiO, Sb2O3, and the mixed material was calcined at 800 ℃ stability, coverage and chemical structure of rutile.
The powder can be used to produce ceramic and ferrite. Nickel powder commonly used in the ceramics industry as a coloring agent. In addition, the adhesion between a filament and ferrite. This makes the surface smooth and stick tight. Ferrite material is relatively new ceramic mainly used for electrical equipment with high frequency. Now China is the largest consumer in the world and the largest producer of stainless steel. It ‘s also the largest producer of hard metal and artificial diamond producing countries in the world. Although the show is also a strong demand for raw materials, which are applicable in these areas. The raw materials are nickel powder. In 2011, the consumption of nickel is almost 120kt. It ‘also the highest in the world.
