Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
The high temperature resistant materials include refractory materials and heat resistant materials, and there are inorganic compounds and high molecular polymer materials.
A refractory material generally refers to an inorganic material that can withstand temperatures above 1580 °C. They are building kiln, combustion chambers and other building materials that require high temperature resistance. Generally made of quartz sand, clay, magnesite, dolomite, etc., high temperature heat insulation coating Zhisheng, is a component of inorganic coating, high temperature resistant casing temperature resistance range -80-1800 °C The thermal conductivity is 0.03W/mK, which can suppress the heat radiation and conduction heat of high-temperature objects and low-temperature objects, and can maintain 70% of heat for high-temperature objects without loss. Zhisheng Coating coats the surface of the object at 1100 °C with 8mm high temperature insulation coating, and the surface temperature of the object can be reduced from 1100 °C to 100 °C. In addition, the high temperature resistant thermal insulation coating is also characterized by insulation, light weight, convenient construction and long service life. It can also be used as an inorganic material for high temperature and acid and alkali resistant glue, Ceramic Substrate Hybrid Integrated Circuit Sheet and the attached object is firm. Such as refractory cement, magnesium bricks, etc. In a broad sense, inorganic fire-resistant high-temperature casing and heat-resistant materials mean that these compounds have high hardness, good brittleness, good chemical corrosion resistance, and a melting point of 1500 or higher. For example, high-temperature glass is also a refractory material. Mainly divided into metal and non-metal compounds and non-metal compounds. The former such as tungsten, molybdenum, niobium, tantalum, vanadium, chromium, titanium, zirconium and other refractory metals and rare earth metal boride, carbide, nitride, silicide, phosphide and sulfide; the latter such as boron carbide, Silicon carbide, boron nitride, silicon nitride, boron phosphide, silicon phosphide, and the like. The latter has extremely important applications and can be used as high temperature refractories (such as abrasives, molds, nozzles, high temperature thermowells), heat resistant materials (such as rocket structural components, nuclear engineering materials, electric heating elements), electrical materials ( Such as high temperature thermocouples, ignition electrodes), but also used as chemical resistant materials and hard 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.
