Different from the artificial diamonds that people are familiar with, the hardness of cubic silicon carbide developed by Professor Wang Xiaogang of Xi'an University of Science and Technology has reached a Mohs hardness of 9.6-9.7.
Our application in aviation
“Professor Wang was a patent obtained in 2003 and a pilot test completed in school in 2008.†Fan Zimin, general manager of Xi’an Bor New Materials Co., Ltd. said that according to the rules, the products can be mass-produced after the completion of the pilot test. Where can a company that manufactures new blank domestic products be established? This is Wang Xiaogang, who needs to be the chief scientist and chairman of the company, to think twice. “After a few years, on the one hand, we continue to develop a series of products, on the one hand, expand the application market of products.â€
According to Fan Zimin, the cubic silicon carbide developed by Bor is not only high in hardness, but also has excellent properties such as anti-wear, high temperature resistance, thermal shock resistance, corrosion resistance, radiation resistance and good semi-conductivity. Before its core technology, only Japan and the United States A few developed countries such as France, Germany, and Germany have mastered it. "There are such new materials with stable physical properties, which are especially suitable for use as precision-machined abrasives and abrasives." He said that the precision-machined abrasives and abrasives are mostly synthetic diamonds, while the cost of cubic silicon carbide is only synthetic diamonds. One-eighth to one-tenth, which gives it a huge market potential.
“After our investigation, we believe that the aviation industry strongly supported by the country needs to use a large number of precision-machined abrasives and abrasives. This is the industry we should take the lead in.†Fan Zimin said that it is timely that the aviation base has gathered a lot. The aviation industry and the development of the industry have strengthened their confidence in firing in the aviation base.
So in 2013, Xi'an Bor New Materials Co., Ltd. signed a contract with the aviation base. After more than a year of construction, trial production began in July last year.
Our market is in the country
Only half a year after it was put into production, silicon carbide brought Borger a revenue of three million. "This is just the beginning. We haven't finished building it yet." Fan Zimin said that the first phase of the design of six sets of equipment, and now only the first set. "We are now building fast, and the remaining five sets are expected to be completed and put into production by the end of this year." He said that the design capacity will reach 500 tons and the output value will exceed 100 million yuan. “Our vision is to produce 3,000 tons per year with an output value of 600 million.â€
The reason for setting such a leap-forward development goal is that Fan Zimin said that this is mainly due to the recognition of three-dimensional silicon carbide in more industries. "This ultra-hard and ultra-stable material can be used not only in aerospace, but also in the military industry, precision processing, electronic information, petroleum smelting, building materials and many other military and civilian industries."
He said that one of the customers that the company is currently negotiating is the ceramic tile industry. "The polishing of ceramic tiles is actually ground, so the demand for silicon carbide in ceramic tile production can be imagined. In addition, fireproof materials, bearing processing, steelmaking deoxidizers, etc. It is our application industry that focuses on tackling key issues."
After the establishment of the aviation industry, Bor's new materials began to rapidly spill their technical strength into many civilian fields to reduce the abrasive costs of these industries. This is not the ultimate strategic goal of Bohr. "We ultimately hope to replace the equivalent diamond market." Because as long as it can be used in synthetic diamonds, it is basically possible to use silicon carbide with comparable hardness and lower price. (This article is reproduced from Xi'an News Network.
