zirconia milling balls

Zirconia balls are now a popular abrasive, used for material dispersion, grinding, now lithium iron phosphate, MLCC, paint, lithium battery anode and cathode, carbon black grinding all rely on our zirconia beads.

The particle size of the grinding is a thousand times the relationship, such as 0.1mm zirconia beads can be ground to 0.1 micron, that is, 100 nanometers, 0.05mm zirconia beads can be ground to 0.05 micron, that is, 50 nanometers, to date the smallest 0.03mm, can be ground to 30 nanometers, this is a good news for inkjet ink, The plug risk is greatly reduced when printing, so for many substances, finer grinding means better performance.

Zirconia balls are also divided into different types.

1. By composition

Zirconium silicate balls

Zirconium silicate balls are a little yellow, the price is relatively lower than other types of zirconia beads, because the silicon content is high, so the cost is relatively low.

The zirconia content is 65%, the silicon oxide content reaches 35% to 39%, and the bulk proportion is relatively low, which is 2.6g/cm3

The most common size for making zirconium silicate beads is 0.6-15 mm.

Application industry: gold, silver, nickel, zinc and lead ore, paint, coatings, pigments and ink heavy calcium, zirconium silicate, titanium dioxide grinding.

2, zirconium aluminum composite balls

Zirconium-aluminum composite balls are added with alumina, of which the zirconia content is about 35% and the alumina is 50% to 60%.

The density is as high as 5g/cm3, and the reactor gravity is 3.1g/cm3

Advantage: When grinding heavy calcium, the whiteness is significantly improved.

Second, according to the type of stabilizer

Because the process of making zirconia balls is like we make glutinous rice balls, the flour itself with water is cohesive and can be directly rolled into a ball, but if it is a ball of sand, no matter how to rub it, it can not make a shape, but if you add some mud, you can make these sand shapes, but the main role is "sand", so how to control the proportion of mud is the most important, More affects the performance, less affects the ball,.

1, yttrium stabilized zirconia balls

Zirconia balls

Yttrium stabilized zirconia balls

Also known as 95 zirconia beads, after the industry's test, with 5% yttrium oxide as a stabilizer, the stabilizer is the auxiliary zirconia forming, zirconia content and as high as possible, so that the performance is stronger, finally found that the highest zirconia content of 95%, the remaining 5% is to do stable materials, after sintering, found that the performance is better than other types of zirconia beads, Whether it is wear, slice, or hardness, toughness, all meet the requirements, and superior.

Take a look at the parameters of our zirconia beads. The specific gravity of yttrium stabilized zirconia beads is 60% higher than that of ordinary zirconia beads, and the density is 6.0g/cm3.

Zirconia 95%, yttrium oxide 5%. Note that this data is approximate value, the actual production is slightly different.

Vickers hardness of more than 1200, this is the result of high zirconia content.

Size: 0.05-10mm, suitable for most needs, high speed sand mill operation is no problem.

Sphericity: 98 or above

Material contamination: Some suppliers (such as Sano zirconia beads) have food safety certification, which means that there is no pollution to the material, so grinding drugs, grinding food, can be used with confidence.

The packaging is 25kg barrel, if the amount is large, there are tons of bag packaging.

Applications:

Coatings, textiles, magnetic materials (ferric oxide, etc.), medicine, food and cosmetics, structural ceramics, electronic ceramics, etc., are applicable to a lot of industries, basically all covered.

2, cerium stabilized zirconia balls

Cerium stabilized zirconia ballsThis is a zirconia balls with cerium oxide as a stabilizer, which has a high density and is widely used for grinding high-viscosity materials, such as paper grinding, chemicals, pesticides, fuels, etc.
