Alumina Ceramic Crucibles
Product Description
Alumina Ceramic Crucibles are made of 99% high purity alumina powder, which gives them excellent chemical stability and thermal shock resistance. Due to the use of high temperature resistant materials, they can be used under 1650℃ for long time. Besides, there are sufficient stocks of various specifications of the products, and special sizes can be customized.
Product Advantages
1. Alumina Ceramic Crucibles have excellent chemical stability and thermal shock resistance.
2. They are easy to wash and keep clean. The glazed surface of the products are bright and delicate, and they are easy to wash away after being stained.
3. They are chemically stable and durable.
Product Application
Alumina Ceramic Crucibles can be widely used in various laboratories, laboratories, analysis of metal and non-metal samples and melting materials and various industrial analysis.
