Properties and Application of Chromium Corundum Brick.
Fire resistance of the product
In the high-purity corundum material by adding Cr2O3, regardless of the amount of how much, not only will not reduce the fire resistance of materials, but to improve the fire resistance of materials. Chromite corundum bricks (> 1790) are superior to high purity corundum products in terms of fire resistance and load resistance (> 1700!).
1. The strength of the product
Room temperature compressive strength of high purity corundum brick is usually 70 ~ 100MPa, room temperature high compressive strength of high-performance chrome corundum brick is generally greater than 150MPa, the intensity was significantly higher than corundum brick. This is because the products in the combustion process, between particles and particles, particles and fine powder, powder and powder formed between the Al2O3-Cr2O3 solid solution, solid solution particles and fine powder particles together, so that the strength of the material to achieve greatly increased.
2. Thermal shock resistance
When the Cr2O3 content is 10% to 66%, Cr2O3 is added to the corundum. Raw materials Chromium Corundum series of products using alumina and chromium oxide with a certain proportion of high-temperature melting after the synthesis of solid solution
