The optimal choice for the preparation of high purity alumina crucibles is alumina (Al2O3) with purity higher than 99%. The choice of raw materials will directly affect the production quality of alumina ceramic crucibles. So, what is high purity alumina?Why is high-purity alumina the first choice for preparing high-purity crucibles?
what is high purity alumina?
Alumina can be divided into high-purity type and common type. The purity of high-purity alumina Al2O3 is greater than 99%, and the sintering temperature is as high as 1650 ° C to 1990 ° C. The purity of ordinary alumina Al2O3 is less than 99%, and sometimes Al2O3 with a purity of 80% or 75% is also classified as ordinary alumina series.
High-purity alumina is the basic material for producing heat-resistant, wear-resistant and corrosion-resistant products. High-purity 99% alumina is usually used to make high-purity alumina crucibles, integrated circuit substrates, special wear-resistant materials, etc., which cannot be achieved by ordinary alumina. Ordinary 95% alumina is mainly used as wear-resistant parts, and 85% alumina is often mixed with some talcum powder to improve electrical properties and mechanical strength. It can be sealed with metals such as molybdenum, niobium, and tantalum, and some are used as electric vacuum devices.
Why is high-purity alumina the first choice for preparing high-purity crucibles?
This is because related industries and laboratory users have high requirements on the quality of crucibles. A poor-quality high-purity crucible will not only affect the experimental results, but may directly lead to the failure of the experiment. The particle size of high-purity alumina can be controlled according to the process, the particle size distribution is uniform, and the chemical properties are stable. Using it to prepare high-purity alumina crucible products can make the produced alumina crucible have the advantages of good electrical conductivity, high wear resistance, corrosion resistance, and low thermal expansion coefficient, which can meet the quality requirements of users.
In this regard, Johncera Group uses 99.7% Japanese low-sodium alumina to produce
high-purity alumina crucibles. Johncera Group can customize high purity crucibles in a variety of shapes and sizes, making high purity alumina crucibles perfect for a variety of applications. Including: powder heat treatment, lithium battery cathode material heat treatment, electronic products and phosphor powder sintering, piezoelectric and dielectric electronic material heat treatment, chemical analysis, etc.
Generally speaking, high-purity alumina is widely used in the preparation of high-purity crucibles because of its superior properties. As a professional manufacturer of high-purity alumina crucibles, Jiangci Group strictly controls every checkpoint, and has been highly praised in terms of user experience and user satisfaction.
