The equipment lining ceramics uses zirconia and alumina, the advantages of these two materials.
Comparison of ceramic toughness: The toughness of zirconia ceramics is 4 times that of alumina ceramics. At the same time, the free fall of zirconia from a height of one meter will only cause some gaps in the alumina to break.
Density comparison: The density of zirconia ceramics is twice that of alumina ceramics. In contrast, zirconia has better compressive performance.
Comparison of friction coefficient: The friction coefficient of zirconia ceramics is only 1/2 of that of alumina ceramics.
Density comparison: The density of zirconia ceramic structural parts is higher than that of alumina ceramics. The density of alumina ceramics is 3.5, the density of zirconia ceramics is 6, and the texture is more delicate. After grinding, the surface finish is higher and can reach 9 or more.
Surface finish comparison: The zirconia ceramic structure has a higher surface finish, mirror-like, extremely smooth, and has less friction. In addition, the zirconia ceramic structure has excellent toughness, overcomes the inherent brittleness of the ceramic itself, and has higher wear resistance, The service life of the product is greatly extended.
Generally speaking, zirconia is more wear-resistant and corrosion-resistant than alumina, and of course, the price is slightly higher.
