High Purity 95% Yttria Zirconia Beads
product description
Yttrium stabilized zirconia beads also known as 95 zirconia beads, after the industry's test, with 5% yttrium oxide as a stabilizer, stabilizer is auxiliary zirconia forming, zirconia content and as high as possible, so that the performance is stronger, and finally found that the highest zirconia content can be 95%, the remaining 5% is to do stable materials, after sintering, It is found that the performance is better than other types of zirconium beads, whether it is wear, slice, or hardness, toughness, all meet the requirements, and superior.
The true density of zirconia beads is 6 grams per cubic centimeter, the packing density is 3.6 grams per cubic centimeter, the density of zirconia beads has Vickers hardness and Mohs hardness, good zirconia Vickers hardness to more than 1250, zirconia ball hardness and alumina ball hardness, fracture toughness is more than twice the alumina ball, so zirconia ball is not easy to be destroyed when under pressure, In this way, wear is very low. The higher the material requirements, the more high-quality zirconia balls must be used to ensure normal production.
There are many things to pay attention to in the use of zirconium beads, can not use low quality zirconium beads, so before the use of zirconium beads should be tested a number of indicators, the first is to use a press test crushing strength, low strength zirconium beads will have broken beads phenomenon, and then the degree of sphericity, low sphericity, even with a small tail zirconium beads are very easy to break, high sphericity more wear-resistant, Also look at the internal structure, we can make a slice of zirconium beads, look at the internal structure, if the texture inside is not uniform, wear will be high; Finally, look at the size distribution, the narrow distribution of zirconium beads, grinding out the material particle size distribution is also narrow, you can use the vernier caliper random detection of the size of multiple zirconium beads to understand the distribution interval.
