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 (FAQ)

Q What are the main grades of Mg-PSZ powder and how do they differ?
Mg-PSZ powder is available in three main grades: ceramic grade, oxygen determination grade, and refractory grade. The differences between grades are achieved by adjusting the MgO content during a specialized production process, resulting in variations in density, bending strength, hardness, and sintered color — ranging from white and grey-white to yellow and earth yellow.
Q What industries use Magnesium Stabilized Zirconia (Mg-PSZ) powder?
Mg-PSZ powder is 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 (refractory linings in furnaces and crucibles for melting superalloys and specialty glasses).
Q What is the recommended sintering temperature for Mg-PSZ powder?
The recommended firing temperature is 1600 ℃. For optimal strength and toughness, ceramic parts should be naturally cooled to 1400 ℃ and held at constant temperature for 5–10 hours. For best thermal shock resistance, parts should be naturally cooled to 1100 ℃ and held at constant temperature for 5–10 hours. The exact firing cycle depends on the size of the workpiece.
Q What purity levels can be expected from Mg-PSZ powder?
Our Mg-PSZ powder maintains very high purity. The ZrO₂+(HfO₂) content ranges from 95.65% to 96.65% depending on the grade. Impurities such as Al₂O₃, SiO₂, Fe₂O₃ are all controlled to ≤0.01%, and CaO is kept at ≤0.02%, ensuring consistent and reliable performance in demanding applications.
Q What are the physical properties of sintered Mg-PSZ ceramic parts?
After sintering, Mg-PSZ ceramics exhibit a density greater than 5.5–5.75 g/cm³ (depending on grade), bending strength of 450–650 MPa, and Vickers hardness (HV) exceeding 1000–1200 MPa for applicable grades. The firing shrinkage is typically 20–24%, and the material demonstrates good to excellent corrosion resistance across all grades.
Q Why does Mg-PSZ powder come in different colors after sintering?
The color of Mg-PSZ after sintering — white, grey-white, yellow, or earth yellow — is determined by the specific formulation and production process used for each grade. White variants (FR-3M01, FR-3M01B) are typically used for structural and anti-corrosion ceramics, while yellow and earth yellow variants (FR-3M02, FR-3M02B, FR-3M03) are suited for refractory and high-temperature structural ceramics applications.
