Suoyi produces industrial-grade yttrium-stabilized zirconia powder (YSZ) in 3Y, 5Y, 8Y, and 13Y grades.

Suoyi produces industrial-grade yttrium-stabilized zirconia powder (YSZ) in 3Y, 5Y, 8Y, and 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.
