Mg-PSZ Powder for Ceramics and Refractories
Mg-PSZ Powder – High-Performance Material for Ceramics, Refractories, and Oxygen Sensors
Overview
Mg‑PSZ (Magnesia‑Partially Stabilized Zirconia) powder is a high‑quality zirconia‑based material produced through advanced electric arc melting processes. By precisely controlling the MgO (magnesia) content, we offer a range of grades suitable for diverse applications. The powder is available in two main types: white and yellow/earthy‑yellow, each formulated for specific end‑uses.
Product Types and Applications
-
Ceramic grades: Used for manufacturing structural ceramics, corrosion‑resistant ceramics, and refractory ceramics. The material offers high strength, good thermal shock resistance, and excellent chemical stability.
-
Oxygen sensor grades: Featuring uniform dispersibility and good thermal stability, this powder is suitable for injection molding and hot pressing in the production of oxygen sensors.
-
Refractory grades: Produced from high‑purity MgO and ZrO₂, melted in electric furnaces. The stabilization degree can be adjusted according to customer requirements, typically around 70%.
