Company profile:
Hebei Suoyi New Material Technology Co., Ltd. has two zirconia grinding balls with a monthly output of 500 tons. We adopt the yttria stabilized zirconia alumina composite(ZTA), and cerium stabilized zirconia powder, according to the condition and grinding process, we adopt isostatic pressing molding technology, sintering technology and processing technology, with high density refined, good abrasion resistance, good roundness and accurate dimension etc.
Speciality:
1. Extremely low abrasive wear(ppm), preventing materials from being polluted.
2. Suitable for the environment of high viscosity, wet grinding and dispersion.
3. High grinding effciency.
4. Long-time working life, lower running cost.
Applications:
1. Low doping requirement industries: magnetic material, piezoelectric ceramics and dielectric ceramics.
2. Pollution prevention industries: medicine industry, food industry and cosmetic industry.
3. Abrasion and corrosion resistant industries: coatings, textiles industry, color industry, printing and dyeing industry.
4. Different ceramic material industries: electronic ceramics, refractory ceramics and structural ceramics.
