Frequently Asked Questions
It is mainly used for high-temperature sample processing such as melting, calcination, sintering, and laboratory testing.
The lid helps reduce contamination, limit sample loss, and maintain a more stable heating environment inside the crucible.
The size should be selected based on sample volume and furnace chamber space, ensuring enough expansion space during heating.
Cracking may occur due to rapid temperature changes or mechanical impact, so gradual heating and cooling is recommended.
Yes, alumina crucibles can be reused if they are not chemically contaminated or physically damaged after use.
Yes, cleaning is recommended to remove residual materials and maintain consistent performance in subsequent experiments.
Alumina crucibles are suitable for many inorganic materials, but strong hydrofluoric acid and certain alkali conditions should be avoided.
Yes, custom sizes, shapes, and technical specifications can be produced according to application requirements.
