Now the company have been the greatest base that scientific researchs and produces carbonyl serial products in our country and in the Asia relying on production and technique experience which is obtained from production of carbonyl products for more than 30 years.We began to produce it in the 1960’s and used it in nuclear industry.
We have been successful in developing micrometer-grade carbonyl Ni powder in 1974 and have acquired national science congress magnificent result award in 1978.It has been tested and appraised by the department, and, acquiring the province and the department high-quality product award in 1983.In 1984, it acquire national economic and trade commission[jinlong]award and in 1985 national silver medal.In1987, states standard for it was published.At present only our company can formally produce this kind products in the Asia.
Apparent shape of Micrometre-grade carbonyl Ni powder is very complicated. It may be little chain,equiaxial,spherical and indented spherical form etc..The apparment density is little, the apparent area ratio is great,the activity is great, the purity is high. It can be compacted and sintered well.It can be even easily diffused in alloy-base with uniform way to obviously heighten quality and property of all kinds powder produts. Our products have been widely used in filter, war industry, adhesive of high density and high melting point material, additive of powder metallurgy, precise alloy, special type steel, stainless steel welding trode, catalyst used in petrochemical industry and new compounds, gas absorbent(used in kinescope),high or ultra-high frequency magnetic mat, CD-Ni battery,etc..
The powder that our company produce has below basecal apparent shape: spherical and onion. Its purity is high, activity is great, its size is fine, just because these individual properties it can be used in national defense, electronics industry,metallargic industry, chem.. engineering, mechanical industry, food industry, medicines and chemical reagents, agriculture and so on. Same as microwave absorbent(hiding mat.),autobalance rectifier, magnetic conduction electron medium iron core, high frequency magnetic core, soft magnetic mat.(use in paper money etc.),all kinds of iron-making powder metallugry, hard alloy, diamond tool,chem.. catalyst, electromagnetic powder clutch, food and medicine additive, optimizing seeds in agricultur ets..
Since its individual property, for example, great activity, little size, good ability of forming and sinterring, relying on these characters, we can add minimal quantity the powder in iron-making powder metallugry to improve its inner property and apparent quality; relying on characteristic of particulate texture, we can make magnetic conduction electron medium iron core, high frequency magnetic core and varied soft magnetic mat; relying on high carboxylation selectivity(to abstract Si, S, P, As poisonous mat.etc.) and high activity, it can be used in chem. Engineering catalyst and food industry; relying on high purity and great activity, the powder can be taken as high density tungsten alloy additive to prevent it from forming brittle-phase; relying on stability of electromagnetic parameter, the powder can be taken as additive mat. That be used in electromagnetic powder clutch and brake unit in the powerful magnetic field; According as need of national defense, iron fibre or micrometer-grade, nanometer-grade superfine carbonyl iron powder can be obtained and took as microwave absorbing mat. With good stability and rather wide absorbing frequency band. Besides, the powder actually is rather widely used in these realms: flaw detection, image magnetic record, agriculture and medecine.
