Difference Between Zirconia and Aluminum Oxide | …
2019/7/31· But, above all, the key difference between zirconia and aluminum oxide is that zirconia occurs in a monoclinic crystal structure while aluminum oxide is in the trigonal crystal structure. Moreover, zirconia is slightly basic because it reacts slowly with strong acids such as HF and sulfuric acid; however, aluminum oxide is amphoteric , and it can react with both acids and bases to form a salt
Boron Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%.
