The difference between aluminum oxide ceramic crucibles and evaporating vessels

Many people are not familiar with the difference between Aluminum oxide ceramic crucibles and evaporating vessels. Although there are many similarities between the two in use, there are still significant differences in actual use.

1. Different uses

Aluminum oxide ceramic crucibles can heat non aqueous substances, such as melting non corrosive salts, igniting precipitates, carbonizing or ashing certain complex specimens, etc; Evaporating dishes are generally used to evaporate solutions.

2. Different materials

The material of aluminum oxide ceramic crucibles must be resistant to high temperatures, and the upper temperature limit for ceramic crucibles is about 800 degrees Celsius; Aluminum oxide ceramic crucibles can be used at high temperatures above 1000 degrees Celsius, while evaporating vessels are usually made of ordinary glass or ceramics, and should be used at temperatures below 400 degrees Celsius.

3. Different heating methods

The aluminum oxide ceramic crucible can be directly heated or placed in a high-temperature heating furnace for heating; Ceramic evaporating dishes can also be heated directly with an open flame, while glass evaporating dishes usually need to be padded with asbestos mesh to be heated.

4. Due to the fact that crucibles are commonly used instruments in thermogravimetric analysis and have very precise quality requirements, it is generally necessary to use waste crucible pliers when using crucibles; The evaporating dish is usually taken by hand, and a glass rod or spoon can be used to transfer reagents.

5. The main purpose of aluminum oxide ceramic crucibles is to burn and precipitate, which can be used for high-temperature treatment of samples, such as ashing, charcoal burning, etc. The aluminum oxide ceramic crucible can withstand high temperatures of 1500 degrees Celsius. Ceramic evaporating dishes are mainly used for evaporating and concentrating liquids. When not subjected to quantitative analysis, they can also be used for drying solids, ashing filter paper, and high-temperature calcination (below 500 degrees Celsius).
