In recent years, industrial ceramics have been widely used in all walks of life, among which alumina ceramics and zirconia ceramics are particularly common. These two ceramic materials have their own strengths, and many companies do not know how to choose. Now let's analyze what are the differences between alumina ceramics and zirconia ceramics?
The difference in density:The density of zirconia ceramics is twice that of alumina ceramics, and the compressive properties of zirconia are better.
The difference in density:The density of zirconia ceramic structural parts is higher than that of alumina ceramics. The density of alumina ceramics is 3.7-3.95, the density of zirconia structural parts is 6, and the texture is more delicate. ▽9 or more.
Differences in surface finish:The surface finish of zirconia structural parts is higher, mirror-like and smooth, which reduces friction with other accessories and has a longer service life. In addition, the toughness of zirconia ceramics is good, which overcomes the inherent brittleness of ceramics, has higher wear resistance, and greatly prolongs the service life of the product.
Differences in ceramic toughness:The toughness of zirconia is 4 times that of alumina ceramics. At the same time, the zirconia ceramics will only have some gaps when dropped freely from a height of one meter, and the alumina will be broken.
Differences in insulation properties:The insulating properties of alumina are better than those of zirconia.
