custom made technical Silicon Nitride Ceramic Tube ferrule
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Cubic boron nitride (CBN) has a cubic crystal structure, its hardness is high, second only to diamond, and has better thermal and chemical stability than diamond. It can be used for hardened steel, wear-resistant cast iron, thermal spraying materials, nickel and other difficult processing Cutting of materials. Can be made into knives, abrasive tools, wire drawing dies, etc.
Other tool ceramics include alumina, zirconia, silicon nitride and other ceramics, but they are not as good as the above three tool ceramics in terms of comprehensive performance and engineering applications. Fine ceramics have emerged in ceramic materials, which dominate the world of new materials with excellent properties such as high temperature resistance, super strength, and multi-function. Fine ceramics refer to high-performance ceramics sintered with precise control processes using refined, high-purity synthetic inorganic compounds as raw materials, so it is also called advanced ceramics or new ceramics. There are many kinds of fine ceramics, which can be roughly divided into three categories-structural ceramics, electronic ceramics and bio-ceramics. Structural ceramics This ceramic is mainly used to make structural parts. Some seals, bearings, cutters, ball valves, cylinder liners, etc. in the machinery industry are parts that are frequently subjected to friction and are easily worn out. Sometimes they are made of metal and alloy and will be damaged after a short period of time. Advanced structural ceramic parts can Withstand this "tribulation". Electronic ceramics refer to functional ceramics used to produce electronic components and structural parts of electronic systems. In addition to mechanical properties such as high hardness, these ceramics can be "indifferent" to changes in the surrounding environment, that is, they have excellent stability, which is very important for electronic components, and the other is high temperature resistance.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
