How to achieve quality control in alumina crucible production?

03 December 2021
Alumina crucibles are made of extremely high temperature resistant ceramic materials. Alumina crucibles are mainly used for melting, burning and refining solid and liquid substances. The quality of laboratory alumina crucibles will have significant impacts on the results of chemical experiments. Therefore, it is particularly important to grasp the quality of alumina crucibles in production. So, how can quality control be achieved in alumina crucible production? Johncera Group will tell you the answer.

How to achieve quality control in lab alumina crucible production?


1.It is very important to have a complete quality control management system. Johncera Group uses high purity, high quality raw materials to produce alumina crucibles in strict accordance with the requirements of the quality control management system. Our high purity alumina crucibles are made from 99.7% Japanese low sodium alumina powder.

2.An important prerequisite for achieving high-quality control in lab alumina crucible production is to fully grasp the knowledge of crucibles. In this regard, our senior team has a comprehensive understanding of ceramics, chemistry, and minerals. At the same time, through extensive international exchanges and cooperation, we are still continuously strengthening our R&D capabilities to achieve world-class alumina crucible production technology and quality level.

3.The production technology of alumina crucibles also affects the quality. Johncera Group produces lab alumina crucibles using traditional slurry casting methods to make the alumina crucible wall in uniform thickness. Moreover, we strictly control the quality to ensure that there are no impurities that may contaminate the sample. In this way, our high purity alumina crucible can significantly improve the accuracy of chemical experiment results by performing good thermal conductivity, excellent thermal shock resistance, chemical resistance, low thermal expansion coefficient, and even heating.

The above points are important factors to achieve quality control in alumina crucible production. Of course, it is also essential to use the lab alumina crucible in the correct way and provide proper maintenance to prolong the service life of the alumina crucible. So, how to use the alumina crucible correctly to extend the service life?

The correct use of lab alumina crucible


1.When the alumina crucible is heated, it needs to be placed on a tripod. When moving the lab alumina crucible, use crucible tongs.

2.After the alumina crucible is heated, it cannot be suddenly cooled down, nor can it be placed on a cold metal table immediately to avoid the crucible from cracking due to the rapid cooling. It should be placed on a tripod to cool naturally.

3.When using the alumina crucible to evaporate, it needs to be stirred, and the waste heat is used to evaporate to dryness when it is nearly evaporated to dryness. When you need to take out the metal solution, take care to take it out with a spoon.

Experimental alumina crucibles with quality control can help improve the accuracy of chemical experiments. In addition, proper maintenance can effectively extend the life of the alumina crucible. In this regard, Johncera Group is a good choice. We have a comprehensive grasp of alumina crucible-related professional knowledge and strictly follow the quality control management system to provide customers with the highest quality products.
