Refractory clay and high temperature cement have their own characteristics in high temperature resistance, and which one is more resistant to high temperature needs to be judged according to specific product types and application scenarios.

I. High temperature resistance of refractory mud

Refractory mud has a wide range of refractoriness, which can range from 1200℃ to 1800℃ according to its composition and use. For example:

Conventional refractory mortar: the maximum long-term use temperature is 1100℃.

High-temperature refractory mortar: the maximum long-term use temperature can reach 1500℃.

Ultra-high temperature refractory mortar: the maximum long-term use temperature can reach 1800℃.

II. High temperature resistance of high temperature cement

High temperature cement usually has a high fire resistance, generally above 1500℃. For example:

The fire resistance of some high-temperature cement can reach 1600℃.

The temperature range of some high-temperature cement is 1000℃ to 1800℃.

III. summary

If only from the perspective of fire resistance, ultra-high temperature refractory cement (fire resistance can reach 1800℃) and some high temperature cement (fire resistance can reach above 1600℃) perform better in high temperature resistance. In practical application, high-temperature cement usually shows better performance in high-temperature environment, especially where high strength, low shrinkage and good sealing are needed.

Therefore, if the application scenario requires higher fire resistance temperature and better high-temperature performance, high-temperature cement may be a more suitable choice.
