Partially Stabilised Zirconia with MgO (3.25%)

Partially Stabilised Zirconia with MgO (3.25%)

The introduction of cold isostatically pressed high purity fine grained zirconia stabilized with MgO (MgO-PSZ) crucibles by Almath Is a significant advancement in high-performance materials for demanding industrial and scientific applications. These crucibles, produced from MgO-PSZ ceramic, bring together a unique set of properties that cater for rigorous applications requiring exceptional durability, thermal stability, and resistance characteristics.

MgO-PSZ ceramics are distinguished by their fine-grained microstructure, which plays a pivotal role in their superior mechanical and thermal properties. This structure is achieved through a manufacturing process that results in a material known for its strength, toughness, and exceptional resistance to thermal shock. Stabilized with 3.25 % magnesium oxide undergoes a transformation toughening mechanism, allowing it to absorb and dissipate energy from mechanical stresses or rapid temperature changes, significantly enhancing its durability and performance under harsh conditions.
Almath produces its own tooling and press bags in house and can offer custom sizes if required. With control over the tooling, the materials and the pressing we can produce what you want in a timely manner.
