For a long time, boron (boron, borax, boric acid) is dominated the boron chemical industry in china, maintain a longer-term roughing system, China produced the borides only 30 to 40 species so far.

Therefore the industry should make great efforts to adjust the product structure of boron to improve the rate of refinement,Industrial road of boron in China Articles efforts to develop the boride varieties of high value-added, to establish boron deep processing system to adapt to the needs of the high-tech development.

Aluminum borate whiskers and magnesium borate whiskers are Chinese new boron-containing material appeared in recent years, wherein the aluminum borate whiskers high elastic modulus, and have good mechanical strength, heat resistance, chemical resistance, acid resistance, electrical insulating properties and in the absorption performance, can be widely used in plastic, metal matrix composites, ceramics, fiber, and other fields.

Magnesium borate whisker has excellent mechanical properties and high temperature resistance, corrosion resistance, and can be applied in aluminum, magnesium alloys and engineering plastics. Add magnesium borate whisker composite materials in addition to excellent strength, abrasion resistance, also different according to the different mechanical properties of magnesium borate whisker content with traditional materials can not match the cost-effective, composite profiles, Price from 100 yuan / kg to 250 yuan / kg range.

From the surveys by metal powder supplier, we know that the global production of rare earth metal boride LaB6 is less than 10kg, far can not meet the demand for new materials industry, the market has great potential. Therefore, the LaB6 market for a long period to stay focused. China has rich rare earth resources, so that the product has a broad development prospects. LaB6 single crystals of the product sales price in more than 100,000 yuan / kg, the powder body and polycrystalline is 30,000 to 40,000 yuan / kg. In addition, crystals of calcium borate in the steelmaking industry, and advanced coatings also have an important role. Since the mid-21st century, with the further development of aviation and space technology, new types of fiber composites have been widely applied to the glass fiber market development opportunities, also greatly expand the application of calcium boride market. The next few years will reach 60,000 to 80,000 tons in the demand for calcium borate. Calcium borate and zinc borate nano products have good fire protection effect, can be used for high-rise building in the cable inner tube, and a coal conveyor belt, ships, trains of various boron cover cloth, etc.

In recent years, many countries boron fiber material gradually penetrated into the field of sporting goods such as golf clubs, tennis rackets, can improve the strength and rigidity of these supplies. In industry, the use of the hardness of the boron can produce a variety of drill bits, ultracentrifugation devices manufactured using boron fibers, high elastic modulus, low thermal expansion properties, superconducting generators, as well as high-speed, high-force rotating mechanical equipment, etc.

The element boron powder and boron isotope products is the nuclear protection of important materials. With the establishment and development of the nuclear power plant in China, its demand is very impressive. International demand of the products, such as automotive safety capsule amorphous boron powder demand of about 15t. Crystalline materials such as ferrosilicon boron transformers and electrical steel sheet alternative material that can be used for refractories, rocket nozzles, high temperature materials. The boron oxide is the main raw material to produce boron powder, metal borides and borate, mainly used in the electronics, semiconductor, boride, iron, and other fields.
