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 through a specialized production process, resulting in different mechanical properties, purity levels, and performance characteristics suited to specific industrial applications.
Q What colors does Mg-PSZ powder come in after sintering, and what applications do they suit?
After sintering, Mg-PSZ powder can appear white, grey white, yellow, or earth yellow depending on the product grade. White and grey white variants are typically used for structural and anti-corrosion ceramics, while yellow and earth yellow types are suited for refractory ceramics and high-temperature applications requiring specific thermal performance.
Q Why is Mg-PSZ powder preferred for thermal barrier coatings (TBCs) in aerospace applications?
Mg-PSZ powder offers superior thermal shock resistance and low thermal conductivity, making it highly effective as a topcoat on gas turbine blades and vanes. These properties protect critical metal components from extreme heat in jet engines and power generation turbines, significantly extending service life and improving operational efficiency.
Q What is the recommended firing temperature and process for Mg-PSZ ceramics?
The recommended firing temperature is 1600 ℃. The firing cycle should be adjusted based on the size of the workpiece. For optimal strength and toughness, parts should be naturally cooled to 1400 ℃ and held at constant temperature for 5–10 hours. For maximum thermal shock resistance, cooling to 1100 ℃ with a 5–10 hour hold is recommended.
Q What purity levels and chemical compositions are guaranteed in Mg-PSZ powder?
Our Mg-PSZ powder maintains ZrO₂+(HfO₂) content above 95.65–96.65%, with MgO at 3.2±0.2 wt%. Impurity levels are strictly controlled: Al₂O₃, SiO₂, and Fe₂O₃ are each kept at ≤0.01%, and CaO at ≤0.02%, ensuring consistent high-purity performance across all product grades.
Q Can Mg-PSZ powder be used in solid oxide fuel cells (SOFCs), and what makes it suitable?
Yes, Mg-PSZ powder is an excellent electrolyte material for SOFCs. Its ability to conduct oxygen ions efficiently at high operating temperatures, combined with its chemical and structural stability, ensures reliable and durable energy conversion performance. These properties make it a preferred choice for next-generation clean energy systems.
