1. High temperature resistance: Alumina ceramic crucible boats can withstand extremely high temperatures up to 1800 ° C without deformation or melting. 2. Corrosion resistance and chemical resistance: Alumina ceramic crucible boats have strong resistance to corrosive environments and are chemically inert to most acids, bases, and molten salts. 3. Mechanical strength and hardness: Alumina ceramic crucible boats have excellent mechanical properties, including high hardness and wear resistance. 4. High thermal shock resistance: The material can withstand rapid temperature changes without cracking or breaking, which is crucial in applications where alumina ceramic crucibles boats are suddenly heated or cooled, such as in thermal cycling processes or quenching experiments. 5. Purity and low pollution: High purity alumina ceramic crucible boats ensures that the material does not introduce impurities into the sample during heating or melting.
