Basic introduction to the performance of alumina crucibles

Alumina crucible has good thermal conductivity, high mechanical strength, high temperature resistance, corrosion resistance, erosion resistance, chemical stability and thermal shock resistance.

1. High temperature resistance: The crucible can be used at temperatures as high as 1750 ℃.

2. Reusable: The crucible used for testing can be washed with water or washed with 10% hydrochloric acid, hot dried (such as in a muffle furnace), and can be reused multiple times.

2. Good heat conduction: the heat transfer speed between the sample pan/crucible is fast, and the temperature distribution is uniform. Generally, sufficient synchronous DSC or synchronous DTA signals can be obtained.

3. Stable structure/performance: The alumina used in the production of crucibles for thermal analysis has a high purity (>99.7%) and is sintered at high temperature to form a dense and uniform microcrystalline structure, ensuring no peaks during the testing process.
