Yttria-stabilized Zirconia Non-Woven Fabric

Yttria-Stabilized Zirconia (YSZ) Non-Woven Fabric offers exceptional thermal resistance, chemical inertness, and flexibility in a porous, fibrous structure. The yttria stabilization ensures phase stability at high temperatures, while the non-woven format provides high surface area and permeability, making it ideal for filtration, thermal insulation, and catalytic substrate applications. Industries use YSZ non-woven fabrics in high-temperature gas filtration, solid oxide fuel cell (SOFC) components, and protective insulation in aerospace systems. Specific uses include particulate filtration in corrosive exhaust streams, catalyst support media for high-temperature reactions, and thermal barrier layers in advanced turbine systems. In research, YSZ fabrics are applied to study gas-solid interactions, optimise catalytic coating adhesion, and explore composite reinforcement in refractory materials. The unique combination of ceramic durability and textile flexibility makes them essential in extreme environment engineering and experimental setups.
