Industrial Ceramic Plate

The industrial ceramic plate has the characteristics of wear resistance, corrosion resistance, electrical insulation and high temperature resistance. The raw materials are industrial technical ceramics, which are inorganic non-metallic materials, and the main content is silicate, which is similar to the composition of the earth's lithosphere. They will not cause soil deterioration and heavy metal ion pollution, and will not affect the ecological environment. Advanced ceramic based plate is a green and environmentally friendly product. Each engineering ceramic material has its own advantages and disadvantages, so full analysis and research must be carried out for the working conditions of ceramics. If the use conditions are not met, the ceramics will not achieve the expected use effect. In general, the main factors that affect the performance of ceramics are as follows: use temperature range and changes; corrosive media; force conditions; hard particles collision incident angle; particle erosion intensity. With the development and progress of the industry, the materials and processes of industrial ceramics are also enriched and improved, making ceramic sheet plates more popular in various industrialization field. The three main applications are shown below.

√ Ceramic Wear Plate

Ceramic has high hardness, reaching Mohs hardness of 8-9, and high mechanical strength. Common wear-resistant ceramics are Alumina, Zirconia, Silicon Carbide and Silicon Nitride. In terms of wear resistance, Alumina < Zirconia < Silicon Carbide < Silicon Nitride, however, the wear resistance of any ceramic material far exceeds that of steel and alloy materials. The cost is the same as the wear resistance, Alumina < Zirconia < Silicon Carbide < Silicon Nitride. Of course, the cost of ceramics is also higher than that of steel or alloys. The application of Alumina plates will be more common, and other materials are more used in industries where cost factors are not considered high. Typical related application areas are wear-resistant linings, bullet-proof plates, wear-resistant and corrosion-resistant carriers, etc.

√ Ceramic Insulating Plate

The common ceramic materials of insulator plates used for electrical insulation are Aluminum Oxide, Zirconium Oxide, Aluminum Nitride, Silicon Nitride and Boron Nitride. There are some differences in performance between different materials, but they generally have low dielectric constant, low dielectric loss, and higher dielectric strength, insulation resistance, etc. In the environment of insulation applications, if you need a particularly high thermal conductivity, you can choose Aluminum Nitride (thermal conductivity as high as 180 W/m.K). If insulation is required, Zirconia with low thermal conductivity is more suitable. In terms of cost, Alumina  < Zirconia < Silicon Nitride < Boron Nitride < Aluminum Nitride.

√ High Temperature Ceramic Plate

High temperature resistance is one of the common characteristics of advanced ceramic materials. Advanced ceramics are made by sintering above 1,000°C. Oxide ceramics, such as 99% Alumina, can withstand a maximum temperature of 1,700°C in an air environment. Silicon Nitride can withstand temperatures of 1,200°C, and the use temperature of Boron Nitride in an inert gas environment is as high as 2,000°C. Moreover, since ceramics also have good corrosion resistance in high temperature environment, they have become very suitable material choices in high temperature environment. However, in addition to the excellent thermal shock resistance of Silicon Nitride and Boron Nitride, the thermal shock resistance of oxide ceramics is not very outstanding, so if it is used in a high temperature environment, it is necessary to control the heating and cooling rate to avoid rapid heating and cooling of the ceramic products cause the explosion of ceramic products. Common related products include setter plates, shed board, and heating board.
