Alumina Block-Alumina Ceramic Block，Al2O3
Alumina ceramic blocks are advanced ceramic materials made from high-quality alumina. We select the highest quality alumina as raw materials, grind it to sub-micron (nanometer) level powder with advanced equipment, and strictly control changes in atmosphere content and temperature during the sintering process to produce high-quality, high-performance oxide Aluminum ceramic.
Alumina ceramics have excellent performance. In terms of high temperature resistance, it can withstand temperatures above 1600°C, and can withstand temperatures up to 1750°C in a specific atmosphere. It is often used in the manufacture of high-temperature crucibles, refractory furnaces, etc. At the same time, its high mechanical properties and chemical corrosion resistance also make it widely used in various wear-resistant parts in industry.
We provide a variety of block alumina ceramics, such as various block insulating parts, ceramic connectors, etc. We can customize alumina ceramic blocks of various sizes for you.
