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. Each grade is produced by adjusting the MgO content during the manufacturing process, resulting in different physical properties such as density, bending strength, and color after sintering — making each grade suitable for specific industrial applications.
Q What colors does Mg-PSZ powder produce after sintering, and what determines the color?
After sintering, Mg-PSZ powder can produce white, grey white, yellow, or earth yellow colors depending on the specific product grade (e.g., FR-3M01 yields white, FR-3M02 and FR-3M02B yield yellow, and FR-3M03 yields earth yellow). The color variation is primarily influenced by the raw material composition and the MgO content ratio used during production.
Q What is the recommended firing temperature and process 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 strength and toughness, the ceramic parts should be naturally cooled to 1400 ℃ and held at that temperature for 5–10 hours. For best thermal shock resistance, cooling to 1100 ℃ with a constant temperature hold of 5–10 hours is recommended.
Q What industries and applications is Mg-PSZ powder most commonly used in?
Mg-PSZ powder is widely used across several high-tech industries. Key applications include Thermal Barrier Coatings (TBCs) for aerospace turbine blades, electrolyte material in Solid Oxide Fuel Cells (SOFCs), oxygen sensors (lambda sensors) for automotive and industrial emission control, and advanced refractory linings for high-temperature furnaces and crucibles used in superalloy and specialty glass melting.
Q What are the typical physical and chemical specifications of Mg-PSZ powder?
The typical specifications include: ZrO₂+(HfO₂) content of 95.65–96.65%, MgO content of 3.2±0.2 wt%, with impurities such as Al₂O₃, SiO₂, and Fe₂O₃ all kept below 0.01%. The sintered density exceeds 5.5 g/cm³ (up to 5.75 g/cm³ depending on grade), bending strength ranges from 450–650 MPa, and Vickers hardness (HV) can exceed 1200 MPa for select grades.
Q How does Mg-PSZ compare in corrosion resistance across different grades?
Corrosion resistance varies by grade. The FR-3M01B and FR-3M02B grades offer "excellent" corrosion resistance, making them the preferred choice for demanding chemical and anti-corrosion ceramic applications. The FR-3M01, FR-3M02, and FR-3M03 grades are rated "good" in corrosion resistance, which is still highly suitable for structural ceramics, mechanical parts, and refractory ceramic components.
