Good Quality Cast Wc Composite Rod - Tantalum-Niobium Carbide TaNbC – WMC

Yttria-stabilized Zirconia YSZ, ZrO₂+Y₂O₃, is a non-toxic, odorless ceramic material. ZrO₂ is monoclinic crystal at room temperature, the phase transformation temperature range of Zirconia is changed to produce stable cubic and tetragonal crystals at room temperature by adding Yttria. Known as “ceramic steel”, Yttria-stabilized Zirconia is usually prepared by hot pressing, dry pressing and isostatic pressing sintering.

As its phase transformation toughening mechanism, Yttria stabilized tetragonal Zirconia crystal ceramic has excellent mechanical properties such as high strength, high fracture toughness, high bending strength, mechanical impact resistance and high wear resistance at room temperature, high ionic conductivity, and excellent chemical corrosion resistance, good stability to acid, alkali, glass and molten metal except sulfuric acid and hydrofluoric acid. With ultra-fine crystal particle size, particle uniformity and reasonable composition ratio, Yttrium stabilized Zirconia has become the primary material for manufacturing oxygen sensors, high-temperature solid fuel cells, piezoelectric ceramics, ferroelectric ceramics, oxygen pumps, cutting tools and as structural ceramic, ceramic ferrule and sleeve, electronic ceramics, super refractory material, optical communication devices and oxygen fuel battery etc.

Yttria-stabilized Zirconia YSZ at Western Minmetals (SC) Corporation can be delivered in composition rate of ZrO₂ 86% + Y₂O₃ 14% in size of powder or ceramic parts as customer’s drawings with package of 10-20kgs in wooden case.
