It has been more than one hundred years since boron carbide powder in manufactured in 1893.Boron carbide powder is applied in many fields from the resistance furnace test to the electric arc furnace production and a horizontal furnace smelting to vertical furnace smelting.
But in past, people were not familiar with it. Now the demand from the world is from several tons to several thousand tons. Chinese output is from dozens of tons / year to million tons / year. Quickly development of boron powder makes the industries surprised.
Boron carbide powder is commonly used in grinding and polishing of carbide, precious stones and other hard materials have a very high grinding capacity is ideal for the hardest man-made abrasive; boron carbide powder has good chemical stability, can resistance to acid, alkali corrosion, and thus as a corrosion-resistant materials to acid, alkali components; boron carbide high temperature, the melting temperature up to 2450 ° C, heat-resistant products and advanced refractory raw materials; boron carbide powder is a high-performance structural ceramics and composite super-hard, ultra-high temperature ceramic materials, often made into a wear-resistant nozzles, water jet nozzle, the mechanical seal ring, mud pump plunger, high temperature, impeller; because of its high hardness, ceramics used aerospace equipment protection, universal application in helicopters, bullet-proof armor, body armor, ship coating; boron carbide powder has good neutron absorbing properties, has been widely used in the nuclear industry, nuclear reactor shielding panels and neutron absorbing pellets.
Boron carbide powder in different areas of mechanical grinding, refractory, chemical, engineering ceramics, the nuclear industry and military applications, the quality of boron carbide are also some differences, their dosage is increasing, so the mass of boron carbide had its The main raw material boric acid present different requirements, and thus beginning to use the boric acid.
Chinese metal powder suppliers locate in Mudanjiang and Heihe, Dalian, Tongliao, Inner Mongolia and Heilongjiang. Existing boron carbide powder smelting capacity of 10000-12000 tons / year, boron carbide processing capacity of over 8000 tons / year. In fact, the plant at full capacity, almost half of existing products for export. In recent years, the level of the boron carbide powder production volatility in demand 2400-3000 tons and foreign demand for 3000-3500, The usage proportion of refractory materials and mixed material is far greater than the amount of grinding and engineering ceramics.
Other metal powder supplier is concentrated in the economically developed countries such as USA, Germany, Japan or other countries. Due to strict requirements on production environment and pollution control, coupled with high costs of energy and labor, there are almost no boron carbide manufactures in other countries. From 2007 to 2008, Chinese exports of boron carbide powder are about 3500 tons. The rigid demand of boron carbide powder and the difference in the prices of Chinese boron carbide powder, it will make developed countries imported boron carbide powder from China. It also promotes boron carbide powder industry to produce required quality and specifications.Source:http://www.mhcmp.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
