This product uses patented technology from Zhenzhong Company, made from zircon sand through electric melting and desiliconization. The product is available in two forms: hollow spheres and solid particles. Thanks to Zhenzhong's unique melting and heat treatment processes, the product possesses high sintering strength and excellent thermal shock resistance, making it particularly suitable for high-temperature materials. With these outstanding properties, this product holds over 70% of the domestic market share in the field of intermediate ladle refractory materials.
High-performance monoclinic zirconia
This product is produced using proprietary technology from Zhenzhong Company. It exhibits a unique coral-like structure at the microscopic level. Compared to ordinary fused zirconia, this product has advantages such as high purity, high activity, large specific surface area, and low sintering temperature. In the field of ceramic pigments, the large specific surface area is more suitable for the use of high-end zirconium-based pigments. In the field of friction braking, the unique coral branch structure significantly enhances the bonding and strength between polymer resins and zirconia particles. In the high-end refractory materials sector, high-performance monoclinic zirconia powder can greatly improve the sintering density of products, enhance thermal shock resistance, and reduce sintering temperature.
Fused calcia stabilized zirconia
Zirconia and calcium yttrium composite stabilized zirconia, produced using the company's patented technology and different grades of zirconia raw materials, are available in two forms: hollow spheres and solid particles. The product's crystal phase composition consists of monoclinic and cubic phases.
Long-life fused calcia stabilized zirconia
This product uses Zhenzhong's unique crystal growth control technology, ensuring complete crystallization development, with grain sizes reaching the centimeter level, and being dense and defect-free. This significantly enhances the erosion resistance against molten steel and slag. The special processing method ensures a high particle packing density, with particle cracks being over 70% lower than ordinary products, making it particularly suitable for immersion water nozzle slag line areas. Its service life is over 40% longer than that of ordinary electric fused stabilized zirconia currently on the market.
Fused magnesia stabilized zirconia
Electrofused magnesia-stabilized zirconia and magnesia-yttria composite stabilized zirconia are produced using zirconia raw materials of different grades and stabilizers such as magnesium oxide, with the product's crystal phase composition consisting of monoclinic and cubic phases.
Fused yttria stabilized zirconia / ytterbium stabilized zirconia
Using different grades of zirconia raw materials, adding varying doses of yttrium oxide and different doses of ytterbium and gadolinium oxides, different types of electric melting yttrium, ytterbium, and gadolinium are produced using special electric melting processes. The stable zirconia raw materials come in two forms: hollow spheres and solid particles, with the product's crystal phase composition being monoclinic and cubic. It can be made into crushed graded powder for plasma spraying.
This product is a fused spherical ceramic sand primarily made of zirconia, which performs exceptionally well in dry or wet sandblasting systems and shot blasting equipment. With its special melting process and advanced screening treatment system, it ensures extremely accurate particle distribution, perfect particle morphology, and an ultra-long service life, significantly reducing manufacturing costs for customers.
This product features a unique material structure, medium density, excellent shape, and strict dimensional range, with a very low proportion of satellite balls and irregular balls. The company strictly follows automotive and aerospace shot peening standards (such as SAE J1830, AMS 2431/7-9) for production and testing. Using this product for shot peening can significantly enhance the fatigue resistance and stress corrosion resistance of the substrate.
Zirconia based thermal spray powders （ZrO₂/Y₂O₃， ZrO₂/CaO，ZrO₂/MgO，Gd₂O₃/ZrO₂，ZrO₂/Y₂O₃-Yb₂O₃-Gd₂O₃)
Zhenzhong Company provides a series of zirconia based plasma spray powders, which are divided into melting crushing and agglomeration sintering according to production processes. The products cover calcia zirconia, magnesia zirconia, gadolinium zirconia, yttria ytterbium gadolinium composite zirconia, and yttrium zirconia spray powders with different yttrium content according to chemical composition. The products are widely used in thermal barrier coatings for gas turbine thermal components.
Yttrium oxide thermal spray powders
Zhenzhong's high-purity yttrium oxide (99.9%) is a agglomerated sintered high-purity Y2O3 powder produced under extremely strict quality control, using Zhenzhong's unique grading and heat treatment techniques. The particle size and strength are strictly controlled in an ideal state, ensuring high purity of the powder and high coating whiteness. It can achieve high deposition efficiency on both mold steel and aluminum alloys, with an average coating hardness of over 600HV. The low coating porosity on mold steel can be controlled below 0.4%.
Yttrium aluminum garnet thermal spray powders
The plasma-sprayed yttrium aluminum garnet powder from Zhenzhong is a high-purity agglomerated sintered spherical powder, produced under extremely strict quality control. It utilizes Zhenzhong's unique classification and heat treatment technologies, with both particle size and particle strength strictly controlled to ideal conditions. It contains 100% yttrium aluminum garnet components, no impurities, high spray efficiency, and low coating porosity.
The product includes a range of magnesium-stabilized zirconia with different magnesium oxide content. The products are divided into original fine powders suitable for mixing injection molding and foam ceramic hanging slurry molding, spray granulation powders for isostatic pressing, and wet granulation powders suitable for dry pressing, to meet different molding processes of customers. The sintered density of the products ranges from 5.0 to 5.75 g/cm³. This series of powders, through a special heat treatment process, ensures that the sintered products have excellent thermal shock resistance and good erosion resistance.
