YTTRIA FELT and FIBERS
TYPE Y
Features
- High Purity
- High Temperature Stability
- Low Thermal Conductivity
- Excellent Thermal Shock Resistance
- Three Product Formats Offered
- Available 'Off the Shelf'
Yttria (yttrium oxide - Y2O3) is typically used as a stabilizer for zirconia. It is offered here in its pure and stable metal oxide form, which is not attacked by most molten metals, including lithium and titanium. Our high purity yttria fiber and textiles are offered in three different standard product forms; bulk fiber Type YBF, two felts Types YF-50 and YF-100.
APPLICATION INFORMATION
Yttria felt is used as thermal insulation for high temperature microwave sintering and in the development of large grain Rare Earth Barium Copper Oxide (REBCO) melt processed high temperature superconductors (HTS).
