Magnesium Stabilized Zirconia Gas Atomizing Nozzles

MgO partially stabilized zirconia (Mg-PSZ) ceramic is an advanced ceramic material with high-performance applications. It is a composite material consisting of zirconium dioxide and a partial stabilization of magnesium oxide. MgO here helps to improve the toughness and mechanical properties than pure zirconia,such as higher fracture toughness, strength, and resistance to thermal shock.


Magnesia Stabilized Zirconia (MSZ) is a great refractory and insulating material due to high oxygen ion conductivity, high strength and toughness, and good thermal shock resistance. It has a clean melt at temperatures above 1900°C and above and is specially manufactured for melting superalloys and precious metals. Its superior thermal shock resistance to temperatures reaching up to 2200°C.

Gas atomization is a technique crucial to produce fine metal powder which can precisely control particle size and composition. In this process, molten metal is atomized into small droplets with high-velocity gas streams. In common way, nozzles is made by materials like tungsten carbide or zirconia ceramic . However, the advent of Magnesium Stabilized Zirconia Gas Atomizing Nozzles introduces a paradigm shift in this domain.


Magnesium Stabilized Zirconia Gas Atomizing Nozzles have emerged as a transformative technology, revolutionizing the metal powder production and shaping the landscape of various industries.
