Product description:
Applications in the field of porous ceramics
In addition to the characteristics of high melting point, high hardness, low thermal conductivity, good thermal stability and small high temperature creep, ZrO2 porous ceramics also have the characteristics of low density, high strength, high porosity, large specific surface area, strong self-interference to fluid and good filtration and adsorption. In addition, the martensitic transformation of ZrO2 can play a toughening effect of phase transformation toughening, microcrack toughening and dispersion toughening, which can greatly improve the toughness and strength of porous ceramics.
Applications in the field of catalysis
Zirconia is a unique oxide, which not only has acidic and basic centers, but also has oxidizability and reducibility, and is prone to strong interaction with the active components of the catalyst. Porous ZrO2 ceramics can be used as an excellent catalyst and catalyst support. Using the high oxygen ionic conductivity of fully stable zirconia, ZrO2 porous ceramics can be widely used in the field of functional materials such as oxygen sensors and solid fuel cell dielectrics.
Application in the field of thermal insulation
ZrO2 porous ceramics combine the advantages of ceramic materials and pore structure, and are widely used in thermal insulation. For example, aerospace vehicles and engineering structural materials ( such as turbine blades, jet engines, etc. ) need special materials to protect them in harsh environments. These protective layer materials not only protect the protected materials from corrosion, wear and erosion, but also play a role in thermal insulation. Making zirconia-based materials into porous ceramics can further reduce thermal conductivity and reduce density. At the same time, the pore structure in porous ceramics can also alleviate the stress caused by thermal expansion mismatch.
Applications in filtration
Zirconia ceramic filter with a maximum service temperature of 1760 °C is widely used to filter various steel castings and large iron castings, high-temperature master alloys and aviation castings, magnetic materials, copper-magnesium alloy continuous casting and non-ferrous metal alloy low-pressure casting.
