Alumina Ceramics:

The creep resistance of alumina ceramics can be increased by three orders of magnitude. If the Si3N4 ceramic material is subjected to 1400-1500 °C high-temperature pre-oxidation treatment, the Si2N2O phase is formed on the surface of the ceramic material, which can significantly improve the oxidation resistance of Si3N4 ceramics. The mechanical properties of Si3N4 ceramics produced by high-temperature strength hot-pressing sintering method are superior to those of reaction-sintered Si3N4. The strength is high, the density is high, the manufacturing cost is high, and the sintering equipment is complicated. Due to the large shrinkage of the sintered body, the dimensional accuracy of the product is limited. It is difficult to manufacture complex parts, and it is only possible to manufacture parts with simple shapes, and the machining of the workpiece is also difficult. The traditional technology process produces high content of powder impurities, high power consumption, low efficiency, and is not easy to form large-scale production. In view of this, nanotechnology experts began to find a way out from the gas phase method research, that is, through the high-temperature gas phase reaction, one step to produce ultra-fine In the gas phase method, the plasma arc gas phase synthesis technology is considered to be the current advanced technology expert. It is believed that this production line developed by Hyde has four innovations: the plasma arc three-stage compression technology is used to make the plasma beam The diameter is limited to less than 10 mm, which is conducive to energy concentration. Secondly, the designed multi-component rapid synthesizing device ensures the chemical vapor phase synthesis of the multi-ambient atmosphere in the plasma arc temperature zone. Third, the nitrogen cooling well is designed. Effectively prevent the growth of powder particles during the gradient cooling wall collection process. Fourth, the gas-solid separation technology and electrostatic collection technology are used to improve the collection rate of nano-silicon nitride powder. The nano-silicon nitride powder prepared by these techniques is used. Body, average particle size is 20 nanometers, purity is 97.5%. According to reports, nano silicon carbide and carbon can be produced on this production line. After a few months of trial production, various powders such as silicon and titanium carbonitride have achieved high efficiency of producing more than 5 kg of nano-silicon nitride powder per hour. Compared with similar products, the production cost has dropped significantly. The price has a strong competitive advantage
