good thermal shock conductivity si3n4 ceramic plate platform
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic Plate:
Silicon Nitride Ceramics brake Si3N4 discs are not ordinary ceramics, but reinforced composite ceramics composed of carbon fiber and silicon carbide at a high temperature of 1700 degrees. Ceramic brake discs can effectively and steadily resist thermal decay, and its heat resistance effect is many times higher than that of ordinary brake discs. The weight of Silicon Nitride Ceramic Disc is less than half that of ordinary cast iron discs. For example, SLR MCLAREN with ceramic brakes has a front wheel brake disc diameter of 370mm but weighs only 6.4 kg. The CL-CLASS, which uses ordinary brake discs, has a front disc diameter of 360mm but weighs up to 15.4 kg. Lighter brake discs mean less weight under the suspension. This makes the suspension system react faster, which can improve the overall handling of the vehicle. In addition, ordinary brake discs are prone to thermal degradation due to high heat under full braking, while ceramic brake discs can effectively and stably resist thermal degradation, and their heat resistance effect is many times higher than that of ordinary brake discs. The Ceramic Disc can produce the maximum braking force immediately in the initial stage of braking, so there is no need to increase the braking system. The overall braking is faster and shorter than the traditional braking system. In order to resist high heat, the brake piston and brake lining There are ceramics between the blocks for heat insulation. Ceramic brake discs have extraordinary durability. If they are used normally, they can be replaced for life, while ordinary cast iron brake discs are usually replaced after several years.
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.
