*The above table shows the specifications and dimensions of common alumina ceramic blocks measured under specific conditions. We can customize alumina ceramics of different sizes for you.
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.
