1. Make tools with ceramic materialsIn machining of metal materials, machining is the most basic and reliable method of precision machining. In modern machining, ceramic tool materials play more and more important roles in high speed cutting and difficult cutting materials due to their excellent heat resistance, wear resistance and chemical stability. Ceramic tool material mainly includes alumina, silicon nitride and theron series. Other ceramic materials such as zirconia and titanium boride are also used as tool materials.2. Alumina seriesPure alumina ceramics contain more than Al 2 O 3 99%, with low strength, poor thermal shock resistance and fracture toughness. Carbide, nitride and boride materials have high strength and hardness and can be used as the reinforcing phase in Al 2 O 3 cera...

Zirconium oxide ceramic materials are usually made by cutting, grinding, grinding and polishing of blank materials. This process requires mechanical processing. The mechanical processing properties of zirconia ceramics include cutting, grinding, grinding and polishing1. Zirconia ceramic cutting, grinding, grinding and polishingZirconia ceramic cutting has three methods: fixed abrasive cutting, free abrasive cutting and single edge cutting. The application and development of high performance industrial ceramics is based on the three-phase composite ceramic material ZTA.2. Plastic deformation of...

In recent years, countries around the world are to shift from traditional ceramic to ceramic, ceramic has been confined to areas such as art, everyday, because of its good heat resistance, biocompatibility, such as performance, is widely used in heat transfer, thermal mechanical, sensitive sensors, optical field, medical areas and in areas such as new energy, is now the focus of national research.The new type of ceramics is superior to traditional ceramics, existing metal or non-metal materials in high temperature, corrosion, abrasion, superhardness and superconductivity. The new ceramic also ...

Zirconium oxide sensor is used to measure the oxygen content in the flue gas of large supercritical boiler furnace by using zirconia ceramic sensor. It is a large number of boiler oxygen content measurement equipment, simple structure, rapid response, accurate measurement and other advantages.Zirconia probe is the use of stable cubic zirconia ceramic in the above 650 ℃ environment produce oxygen ionic conduction properties and design, in a certain temperature conditions, if the zirconium dioxide gases on either side of the block ceramics exist in different oxygen concentration in the zirconium...
