Suoyi Produces Industrial Grade Yttrium Stabilized Zirconia Powder (YSZ) 3Y 4Y 5Y 8Y 13Y Grades

Suoyi Produces Industrial Grade Yttrium Stabilized Zirconia Powder (YSZ) 3Y 4Y 5Y 8Y 13Y Grades 

This information provides complete technical and procurement details for Hebei Suoyi New Materials' industrial-grade yttrium-stabilized zirconia (YSZ) powder, differentiated from dental-grade powders, focusing on performance and selection for industrial applications.

Hebei Suoyi, located in Handan Economic and Technological Development Zone, Hebei Province, is a large-scale zirconia powder manufacturer in China. Its monthly production capacity of industrial-grade YSZ reaches 200 tons, and it possesses independent import and export qualifications. Standard packaging is 25kg plastic drums (lined with PE bags), with custom 50kg/ton bags available. The production process employs chemical co-precipitation + sol-gel + spray granulation, strictly controlling particle size distribution and yttrium uniformity, resulting in strong batch stability.

Yttrium-Stabilized Zirconia Powder Characteristics (Common Characteristics for Industrial Grades)
1. Crystal Form: Room temperature stable tetragonal/cubic phase, free of monoclinic impurities, avoiding phase transformation volumetric cracking;
2. Mechanical and Thermal Properties: High hardness, high fracture toughness, thermal shock resistance; low thermal conductivity, high temperature resistance (melting point ≈ 2700℃);
3. Chemical Properties: Resistant to strong acids and alkalis, does not react with most industrial media;
4. Particle Size: Standard D50 = 0.3–1μm, nanoscale (50nm, etc.) can be customized; controllable BET specific surface area, high sintering activity.

Yttrium-Stabilized Zirconia Powder Application Scenarios
- Thermal Barrier Coating (TBC): Aero-engine, gas turbine blades;
- Industrial Ceramics: Wear-resistant valves, sealing rings, ceramic cutting tools, grinding beads;
- Energy and Electronics: SOFC electrolytes, oxygen sensors, ceramic substrates;
- Refractory Materials: High-temperature kiln linings, crucibles.

Yttrium Stabilized Zirconia Powder: Procurement and Quality Control Key Points
1. COA (Composition Analysis Report), XRD phase structure, laser particle size distribution (D10/D50/D90), BET specific surface area;
2. Differentiate between industrial grade and dental grade: Industrial grade does not emphasize "transmittance," has a wider tolerance for heavy metals than dental grade, and is cheaper; mixed use in medical and dental applications is strictly prohibited;
3. Delivery time: In-stock products, standard specifications, 3-7 working days; customized particle size/yttrium content, 20-25 days.
