Magnesium Stabilized Zirconia Powder: Thermal Shock-Resistant Ceramic

Magnesium Stabilized Zirconia Powder is a high-performance ceramic with excellent thermal stability and mechanical strength. Magnesium oxide as a stabilizer maintains its cubic crystal structure, avoiding phase transitions when temperatures change, thus delivering superior thermal shock and corrosion resistance plus high fracture toughness. It’s widely applied in thermal barrier coatings, solid oxide fuel cells, oxygen sensors and special refractories, and is a preferred material for aerospace, energy and industrial engineering for its reliable performance in extreme environments.

Appearance & Application Matching|Color Variants for Functional Ceramics

Our Mg-PSZ powder can be divided into two types: One is white and the other is yellow and earth yellow, which are applied for different structural ceramics, anti-corrosion ceramics and Refractory ceramics.

Industry Applications|High-Performance Material for Extreme Conditions

Magnesium stabilized zirconia powder is a critical material in high-tech industries due to its exceptional stability and performance under extreme conditions. Its primary applications include:

Aerospace & Power Generation|Thermal Barrier Coatings (TBCs)
Thermal Barrier Coatings (TBCs): It is widely used as a topcoat on gas turbine blades and vanes in jet engines and power generation turbines. The powder’s superior resistance to thermal shock and low thermal conductivity protects metal components from intense heat, significantly improving efficiency and service life.

Energy Conversion Systems|Solid Oxide Fuel Cells (SOFCs)
Solid Oxide Fuel Cells (SOFCs): It serves as a stable, high-strength electrolyte material. Its ability to conduct oxygen ions at high temperatures while remaining chemically and structurally inert is essential for efficient energy conversion.

Sensing Technologies|Oxygen Sensors for Precise Control
Oxygen Sensors: The powder is fundamental in manufacturing lambda sensors for automotive and industrial applications. Its ionic conductivity allows it to precisely measure oxygen levels in exhaust gases, enabling optimal combustion control and reducing emissions.

High-Temperature Engineering|Advanced Refractory Applications
Advanced Refractories: Its high melting point and corrosion resistance make it ideal for linings in furnaces and crucibles used for melting superalloys and specialty glasses, where it withstands harsh chemical and thermal environments.

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.
