Note:

⚠️ Firing Instructions: 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 color after sintering — each optimized for specific end-use applications.
Q What colors does Mg-PSZ powder produce after sintering, and what applications do they suit?
After sintering, Mg-PSZ powder produces white, grey-white, yellow, and earth yellow colors depending on the grade. White and grey-white variants (FR-3M01, FR-3M01B) are typically used for structural ceramics and anti-corrosion ceramics, while yellow and earth yellow variants (FR-3M02, FR-3M02B, FR-3M03) are preferred for refractory ceramics and high-temperature applications.
Q Why is Mg-PSZ powder used in Thermal Barrier Coatings (TBCs) for aerospace applications?
Mg-PSZ powder is ideal for Thermal Barrier Coatings due to its superior thermal shock resistance and low thermal conductivity. When applied as a topcoat on gas turbine blades and vanes in jet engines and power generation turbines, it effectively shields metal components from extreme heat, extending component service life and improving overall system efficiency.
Q What is the recommended firing temperature and process for Mg-PSZ ceramics?
The recommended firing temperature is 1600 ℃, with the firing cycle determined by the size of the workpiece. 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 held at constant temperature for 5–10 hours.
Q Which Mg-PSZ grade offers the highest bending strength and hardness?
Grade FR-3M02 offers the highest bending strength at 650 MPa and the highest Vickers hardness (HV) exceeding 1200 MPa among all listed grades. It also achieves a sintered density greater than 5.75 g/cm³, making it the top choice for applications demanding maximum mechanical performance such as structural ceramic parts and mechanical components.
Q How does Mg-PSZ powder perform in Solid Oxide Fuel Cells (SOFCs) and oxygen sensor applications?
In Solid Oxide Fuel Cells, Mg-PSZ functions as a stable, high-strength electrolyte material, conducting oxygen ions efficiently at elevated temperatures while remaining chemically and structurally inert — critical for reliable energy conversion. In oxygen sensors (lambda sensors), its ionic conductivity enables precise measurement of oxygen levels in exhaust gases, supporting optimal combustion control and emission reduction in automotive and industrial systems.
