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 — 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.
