Oxide composites have special state structure and excellent physical and chemical properties. They are important basic raw materials for high-tech industries and national defense technology industries. They are widely used in aerospace, chemical metallurgy, special materials, energy and communications industries.
From the production of elemental powders to nickel-iron alloy powders by carbonyl method, Jinchuan Group relies on technological innovation and collaborative research to master the synthesis process of nickel-iron alloy powder with finer particle size, higher purity and broad spectrum and high efficiency. “The size of carbonyl nickel iron powder is below 10 microns, which is one-fifth of the particle size of traditional atomized nickel-iron alloy powder.†Chen Zhengqian, head of the marketing department of the group's carbonylation metallurgical plant, said that the carbonyl complex is more active and easy to adapt to each. A complex processing process requires mechanical properties such as stainless steel and synthetic diamond to be stronger.
Purity is the primary measure of rare alloys. The preparation process of the carbonyl method does not react with the transition metal in the raw material, and the metal impurity content of the product does not exceed 0.3% except for trace amounts of non-metallic substances such as carbon, nitrogen and oxygen. The powder particle structure is an "onion layer" structure in which nickel-iron layers are coated with each other, and the uniformity and contact degree are better. "Carbo-nickel-iron alloy powder has the catalytic effect that other similar products do not have, which reduces the application production conditions, and has obvious energy-saving, material-saving and cost-saving effects." Chen Zhenggan said.
The freely blended ferronickel mixture is another feature of the product. The nickel or iron content is adjusted from 10% to 90%. The flexibility and mixing performance are excellent. The downstream industry can be customized according to the needs.
Chen Zhengqian said that the successful research and development of carbonyl nickel-iron alloy powder has changed the global powder metallurgy production pattern, enriched the industrial clusters and industrial chain, and played a positive role in promoting the structural reform of the supply side and “slip reduction and increase profitsâ€.
SiC ceramics not only have excellent mechanical properties at room temperature, such as high flexural strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance). Etc.) is the best among known ceramic materials. Hot press sintering, pressureless sintering, hot isostatic pressing, the high temperature strength can be maintained up to 1600 ° C, which is the best material for high temperature strength in ceramic materials. Oxidation resistance is also the best of all non-oxide ceramics. Alias Emery.
