The industrialization of high value-added boron carbide materials focus on the industrialization of the boron carbide ultrafine powders and high-performance boron carbide ceramics and realizes boron carbide ultrafine powders’ scale production and application.
It will break through the monopoly foreign technology of large size, complex shape in carbon boron chest plate. Great progress has been made and after the milling of boron carbide coarse powder, the median size is about 1 micron. The colloidal processing combined with large size in hot pressing technology and hyperboloid shaped bulletproof chest plate. It has excellent mechanical properties.
Implementation of this project could also contribute to the development efforts of boron resources, promote the upgrading of the boron products, accelerate the industrialization process of the boron powder carbide industry and promote the development of boron carbide relating fields such as aviation, military and nuclear industry.
New boron carbide material is non-metallic refractory compounds and it one of the super-hard artificial materials with hardness only to diamond and cubic boron nitride. Boron carbide ceramic with light weight, high hardness, high corrosion resistance, wear resistance, impact resistance, the neutron absorbing performance characteristics, has broad application prospects in the field of national defense industry, high-tech industries, nuclear power technology. In the military field, boron carbide is the world's most widely used bulletproof ceramic materials. At present, Japan and the United States go in research and development of high-performance silicon powder products have been equipped with a world leader in high value-added boron carbide products in various fields, while Germany is a world leader in the preparation of boron carbide ultrafine powders. Boron resources, but by their preparation of technical limitations, it is difficult to obtain high value-added boron carbide powder and its products and therefore to carry out the industrialization of high-value-added boron carbide is very important.
One of the important innovations of high value-added boron carbide materials industry is the technology of large size, complex shape in the boron carbide ceramic bulletproof chest plate preparation. The technology mainly using colloidal processing methods combined with the hot-pressing sintering, a certain amount of organic matter in the boron carbide ceramic slurry, fabricated performance by controlling the organic content of the slurry viscosity, molding water content and other parameters fine boron carbide ceramic body.
Most of boron carbide manufacturers mainly produce simple shapes such as the low end of the nozzle, the nozzle seal ring ceramic parts, the preparation method is hot pressing sintering, finishing nickel powder products, and high production costs. Several large companies have tried to use the traditional method of preparation of large size, complex shape of the boron carbide ceramics, are failed. Abroad, especially Europe and the United States has boron carbide ceramic materials for troops and equipment.
High value added boron carbide materials industry will completely change the domestic boron carbide industry’s situation that it can only produce a small amount, and low-grade boron carbide products. It improves the product technology content and added value of boron carbide and boron carbide industry's technology level. The production of high quality high-end products will have great significances in meeting the Chinese market and international market demand.Source:http://www.mhcmp.com
