thermal conductivity ceramic plate High temperature resistant and heat insulating alumina and zirconia ceramic plates

Thermal conductivity ceramic plate have a good thermal conductivity ability for industry. thermal conductivity ceramic plate have a high hermal conductivity ceramic plate and low hermal conductivity ceramic plate. all of them depend on the raw of the ceramic plate and also depend on the customer applications.
 

Alumina ceramics and zirconia ceramics each have their own unique characteristics in terms of high-temperature resistance and heat insulation performance.

 

Even in high-temperature environments, alumina ceramics are not easy to melt or deform, and can maintain good stability at high temperatures close to the melting point. Specifically, the sintering temperature of high-purity alumina ceramics (Al₂O₃ content above 99.9%) can be as high as 1650-1990℃, and the temperature resistance range can usually reach above 1500 degrees Celsius, which can remain stable in extremely high temperature environments.

 

As the temperature increases, the strength and hardness of alumina ceramics will gradually decrease. Despite this, at a high temperature of 1800℃, alumina ceramics can still maintain stable performance and are suitable for high-temperature applications such as furnace linings, kiln components and heat exchangers.

 

Zirconia ceramics can withstand the test of factors such as high-temperature corrosion, oxidation and thermal shock, ensuring the normal operation of equipment and extending its service life.

 

The thermal conductivity of alumina ceramics is relatively high at room temperature, about 20~30W/(m·K). However, as the temperature rises, its thermal conductivity will continue to decrease. For example, at 1200℃, the thermal conductivity of alumina is only about half of that at 400℃. The thermal conductivity of zirconia ceramics is extremely low, which means that it can effectively prevent the transfer of heat, thus achieving excellent thermal insulation. Its excellent thermal insulation properties make it an ideal choice for manufacturing thermal insulation ceramic structural parts.

The thermal insulation properties of zirconia ceramics are particularly important in high temperature environments. For example, in the aerospace field, aircraft engines and spacecraft components need to operate in extremely high temperature and high pressure environments, and the high temperature resistance and stability of the materials are extremely high. Zirconia ceramics have become an ideal material for these components due to their excellent high temperature resistance and thermal insulation properties, effectively improving the durability and service life of the equipment.
