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)

1 What are the three main grades of Mg-PSZ powder and how do they differ?
Mg-PSZ powder is available in three grades: ceramic grade, oxygen determination grade, and refractory grade. Each grade is produced by adjusting the MgO content through a specialized production process, resulting in different physical properties — such as density, bending strength, and color after sintering — to suit specific application requirements.
2 What colors does Mg-PSZ powder produce after sintering, and what applications do they serve?
After sintering, Mg-PSZ powder can produce white, grey white, yellow, or earth yellow colors depending on the specific grade. White and grey white variants are typically used for structural ceramics and anti-corrosion ceramics, while yellow and earth yellow variants are suited for refractory ceramic applications.
3 Why is magnesium stabilized zirconia powder used in Thermal Barrier Coatings (TBCs)?
Mg-PSZ powder is ideal for TBCs because of its superior thermal shock resistance and low thermal conductivity. When applied as a topcoat on gas turbine blades and vanes in jet engines or power generation turbines, it effectively shields metal components from extreme heat, extending component service life and improving overall system efficiency.
4 What is the recommended firing temperature and process for Mg-PSZ ceramics?
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 the best thermal shock resistance, parts should be naturally cooled to 1100 ℃ and maintained at constant temperature for 5–10 hours. The exact firing cycle depends on the size of the workpiece.
5 Which Mg-PSZ grade offers the highest bending strength and density?
Grade FR-3M02 offers the highest bending strength at 650 MPa and the highest density at >5.75 g/cm³ among the available grades. It is well-suited for demanding structural and mechanical applications where both high mechanical strength and material integrity are critical.
6 How does Mg-PSZ powder perform in Solid Oxide Fuel Cells (SOFCs) and oxygen sensor applications?
In SOFCs, Mg-PSZ serves as a stable, high-strength electrolyte that conducts oxygen ions at elevated temperatures while remaining chemically and structurally inert — essential for efficient energy conversion. In oxygen sensors (lambda sensors), its ionic conductivity enables precise measurement of oxygen concentrations in exhaust gases, supporting optimal combustion control and emission reduction in automotive and industrial systems.
