Frequently Asked Questions
Alumina square crucibles can be used to hold powders, solids, ash, oxides, and other laboratory samples during heating, calcination, thermal treatment, and material testing. The suitability depends on the sample composition and processing conditions.
Yes, alumina ceramic crucibles are generally suitable for repeated heating and cooling cycles when operated within the recommended temperature range and under appropriate conditions. Avoiding sudden temperature changes can help reduce thermal stress.
Alumina has good chemical stability at elevated temperatures and can be used with many materials. However, compatibility with molten metals depends on the specific metal, temperature, atmosphere, and holding time, so the material combination should be evaluated before use.
Allow the crucible to cool completely before cleaning. Loose residues can usually be removed with a suitable laboratory cleaning method. Avoid aggressive mechanical impact or sudden temperature changes that could damage the ceramic.
An alumina square crucible can be used in furnaces and certain thermal processing or analysis setups when its dimensions and operating conditions match the equipment requirements. Customers should verify the available space, heating temperature, atmosphere, and sample holder configuration before use.
Yes. Custom dimensions, wall thicknesses, shapes, alumina purity, and other specifications can be discussed according to the application and equipment requirements.
