industrial hard strong Silicon Nitride ceramic cutters knives
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Conductive ceramic materials. It is one of the main raw materials of the vacuum coating conductive evaporation boat. Ceramic cutting tools and molds. It can manufacture finishing tools, wire drawing dies, extrusion dies, sandblasting nozzles, sealing elements, etc. Composite ceramic materials. It can be used as an important component of multi-element composite materials. It can be combined with TiC, TiN, SiC and Other Materials to form composite materials to produce various high-temperature resistant parts and functional parts, such as high-temperature crucibles, engine parts, etc. It is also one of the best materials for making armor protection materials. Cathode coating material for aluminum electrolytic cell. Due to the good wettability of TiB2 and metal aluminum liquid, using TiB2 as the cathode coating material of the aluminum electrolytic cell can reduce the power consumption of the aluminum electrolytic cell and extend the life of the electrolytic cell. Made into PTC heating ceramic materials and flexible PTC materials, it has the characteristics of safety, power saving, reliability, and easy processing and forming. It is an updated high-tech product of various electric heating materials. Titanium boride is a very good strengthening agent for metal materials such as Al, Fe, and Cu. Binary compounds formed by boron and metals and certain non-metals (such as carbon). It can be represented by the general formula MmBn, which is generally a mesenchymal compound and does not follow the valence rules. Except for zinc (Zn), cadmium (Cd), mercury (Hg), gallium (Ga), indium (In), thallium (Tl), germanium (Ge), tin (Sn), lead (Pb), bismuth (Bi) In addition, other metals can form borides. They are all crystals with high hardness and melting point. They are chemically stable, and hot concentrated nitric acid can not dissolve them. They can be directly combined with elements or made by reducing oxides with active metals. They are used as refractory, abrasive and superconducting materials.
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.
