Product Description

Silicon Nitride ceramic step shaft rod plunger

Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

Silicon Nitride Ceramics can be used as high-temperature insulating materials. The performance of the silicon nitride ceramics depends mainly on the synthesis method and purity. The free silicon that is not nitrided in the material, the alkali metal, alkaline earth metal, iron, titanium, etc. Magazines such as nickel can deteriorate the electrical properties of silicon nitride ceramics. Generally, the specific resistance of silicon nitride ceramics in the drying medium is 1015-1016 ohms at room temperature, and the dielectric constant is 9.4-9.5. At high temperatures, the silicon nitride ceramics still maintain a high specific resistance value. With the improvement of conditions, silicon nitride can enter the ranks of common dielectrics. Sintered silicon nitride has a low thermal expansion coefficient of 2.53×10-6/°C and a thermal conductivity of 18.42 W/m·K, so it has excellent thermal shock resistance, second only to quartz and glass-ceramics. There are experimental reports that the reaction sintered silicon nitride sample with a density of 2500 kg/m3 is cooled from 1200 °C to 20 °C for thousands of cycles, and still does not break. The thermal stability of silicon nitride ceramics is good, and it can be in high temperature. long-term use. It can be used up to 1400 ° C in an oxidizing atmosphere and 1850 ° C in a neutral or reducing atmosphere.

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.
