Our Mg-PSZ powder can be divided into three types: ceramic grade, the oxygen determination grade and refractory grade.
With special production process, we can produce different Mg-PSZ powder by adjusting the content of MgO.
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.
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:
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.
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.
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.
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.

Our Mg-PSZ powder is classified into three main types: ceramic grade, oxygen determination grade, and refractory grade. We can customize the properties of the powder by adjusting the MgO content based on your application needs.
We offer two main color variants: white, and yellow/earth yellow. These distinct variants are tailored for different application demands, including structural ceramics, anti-corrosion ceramics, and refractory ceramics.
Mg-PSZ is widely applied as a topcoat on gas turbine blades in aerospace and power generation. Its exceptional resistance to thermal shock and low thermal conductivity shield underlying metal components from extreme heat, significantly enhancing operational efficiency and component service life.
Depending on the specific product type (such as FR-3M01, FR-3M02, etc.), the bending strength ranges from 450 MPa up to 650 MPa, allowing you to choose the optimal grade for structural or high-load applications.
For optimal thermal shock resistance, it is recommended to let the sintered ceramic parts naturally cool down to 1400 ℃ or 1100 ℃, and then maintain a constant temperature at that level for 5 to 10 hours during the cooling phase of the firing cycle.
Mg-PSZ (Magnesium Stabilized Zirconia) provides exceptional resistance to thermal shock, high mechanical strength, excellent corrosion resistance, and low thermal conductivity, making it superior for extreme thermal and chemical environments.
