Note: The firing process is carried out at 1600 ℃, and the firing cycle is determined based on the size of the work piece. When applying the strength and toughness of the ceramic parts, it is best to apply thermal shock resistance when the ceramic parts are naturally cooled to 1400 ℃ and kept at a constant temperature for 5–10 hours. When the ceramic parts are naturally cooled to 1100 ℃ and kept at a constant temperature for 5–10 hours, the thermal shock resistance is the best.

Frequently Asked Questions

Q What are the main grades of Mg-PSZ powder and how do they differ?
Mg-PSZ powder is available in three primary grades: ceramic grade, oxygen determination grade, and refractory grade. Each grade is produced by adjusting the MgO content during a specialized manufacturing process, resulting in different mechanical properties, densities, and color characteristics after sintering — ranging from white and grey-white to yellow and earth yellow.
Q What is the recommended sintering temperature for Mg-PSZ powder?
The recommended firing temperature is 1600 ℃. The firing cycle should be adjusted based on the size of the workpiece. For optimal thermal shock resistance, it is advised to hold the temperature at 1400 ℃ or 1100 ℃ for 5–10 hours during natural cooling, depending on the desired balance between strength, toughness, and thermal shock performance.
Q Which industries commonly use Magnesium Stabilized Zirconia powder?
Mg-PSZ powder is widely used across several high-tech industries, including aerospace (thermal barrier coatings on turbine blades), energy (solid oxide fuel cells), automotive and industrial sensing (oxygen/lambda sensors), and high-temperature engineering (furnace linings, crucibles for melting superalloys and specialty glasses).
Q What is the typical density and bending strength of sintered Mg-PSZ ceramics?
The sintered density of Mg-PSZ ceramics typically exceeds 5.5–5.75 g/cm³ depending on the grade. Bending strength ranges from 450 MPa (FR-3M03) to 650 MPa (FR-3M02), making it suitable for demanding structural and mechanical applications. The Vickers hardness (HV) can exceed 1000–1200 MPa for select grades.
Q How does MgO content affect the properties of Mg-PSZ powder?
The MgO content, maintained at 3.2±0.2 wt% across standard grades, plays a critical role in stabilizing the zirconia crystal structure. Adjusting MgO levels influences the phase composition, mechanical strength, thermal shock resistance, and the final color of the sintered ceramic — enabling customization for ceramic, refractory, or oxygen sensor applications.
Q What purity levels and impurity limits does your Mg-PSZ powder meet?
Our Mg-PSZ powder maintains a ZrO₂+(HfO₂) content of 95.65–96.65%, with strict impurity controls: Al₂O₃ ≤ 0.01%, SiO₂ ≤ 0.01%, Fe₂O₃ ≤ 0.01%, and CaO ≤ 0.02%. The specific surface area (SSA) is 8–12 m²/g and the secondary particle size D50 is <1.0 μm, ensuring excellent sintering behavior and consistent performance.
