High strength and toughness — the severe-duty mechanical ceramic. Stabilised forms operate to 2400 °C and resist aggressive metal and slag chemistries.
Used for: atomising nozzles · pump and valve components · cutting tools · oxygen sensors · crucibles · wear parts
Anderman offers a range of zirconia materials, dense or with porosity. These materials combine very high temperature capability (up to 2400 °C in stabilised dense forms) with outstanding performance in high-wear and corrosive environments. Products are available as tubes, rods, crucibles, atomising nozzles and a wide range of custom shapes.
Zirconia’s defining property is fracture toughness — yttria partially-stabilised grades (Y-PSZ) deliver toughness an order of magnitude above alumina, transforming under stress to absorb energy. Thermal conductivity is intentionally low (2–3 W/m·K), making zirconia an excellent thermal barrier.
Pure ZrO₂ undergoes a destructive phase change on cooling. Stabilisation with yttria, magnesia or calcia locks in the tetragonal or cubic phase: yttria gives the highest toughness and the cleanest oxygen-ion conductivity (used in sensors); magnesia and calcia offer lower-cost partial stabilisation.
Atomising and metering nozzles for metal powder production, pump and valve components in chemical service, oxygen-sensor electrolytes, severe-wear inserts, and crucibles for high-purity melting.

Partially-stabilised zirconia contains metastable tetragonal grains that transform to monoclinic under crack-tip stress, expanding slightly and closing the crack — a mechanism called transformation toughening, unique to this ceramic family.
Y-PSZ delivers higher toughness, finer microstructure and better surface finish — preferred for nozzles, cutting tools and structural parts. Mg-PSZ is cheaper and runs hotter, used for less demanding wear or larger geometries.
Yes — in pumps and valves handling acids, alkalis or abrasive slurries, zirconia outlasts metals and alumina by significant factors. Check chemistry against hot caustics and HF before specifying.
