The alumina ceramic boat is a versatile and durable container for thermal analysis testing. It is made of high-quality alumina ceramic, which has the characteristics of high melting point, strong hardness, good chemical stability, etc., and can withstand extreme temperatures, corrosion, and wear. Its smooth surface facilitates sample removal, while its high thermal conductivity ensures the accuracy of temperature readings during testing. It is a good material for high temperature and chemical corrosion resistance. Alumina sample pans are widely used in thermal analysis (such as DTA and DSC) to provide consistent and accurate results in thermal analysis tests.

Advantage of Alumina Ceramics

-High-temperature resistance: long-term use temperature is 1600℃, short-term use temperature is 1800℃ (Al2O3≥99%), suitable for melting, sintering, annealing, and other occasions.

-Low thermal conductivity: minimizes thermal shock and ensures safe operation even under very hot conditions.

-Excellent durability: withstands multiple heating and cooling cycles without cracking or deformation.

-Easy to clean and cost-effective.

-Wide material compatibility: compatible with metals, salts, organics, and various laboratory chemicals.

-Non-toxic and safe for laboratory use.
