Parameters of high temperature refractory silicon carbide plates
The high temperature refractory silicon carbide (HTC) plates typically contain a mix of different components, including:
* High-temperature gas: A mixture of CO2, N2, and H2O to maintain the normal temperature for periods of time.
* Silicon carbide powder: A chemical reaction that produces silane carbides, which have good mechanical properties.
* Silicon nitride: A functionalized, with unique properties such as resistance to corrosion and low heat resistance.
In addition to these components, there may also be other materials present in the form of catalysts, coatings, or pads that can improve the performance of the HTC plates under certain conditions. Additionally, the precise composition and type of materials used in the production of the HTC plates will affect their specific properties and performance.
