Redon zirconia fiber Shaped Parts is made of yttrium oxide stabilized zirconia fiber by special process, does not exist phase changes. This type of product is treated with ultra-high temperature, and can still maintain dimensional stability at 2000 ºC or even 2200 ºC. Zirconia fiber high temperature vapor pressure is small, no volatiles at high temperature, clean, pollution-free.
Redon zirconia fiber profile parts can be processed into various shapes and sizes according to customer requirements. Commonly used density between 1.0g/ CM3-2.0g /cm3, can be produced according to customer requirements. The volume weight is consistent, the surface is smooth and flat, does not drop powder, no gap, low shrinkage.
| Characteristic | High purity Ultra-high temperature without deformation High mechanical strength and machinability Very low thermal conductivity High temperature treatment without organic residue 10wt% Y2O3 Stable crystal phase |
| Application | Used for hot surface heat insulation of a variety of high temperature furnaces; As a variety of high temperature electric furnace, crystal growth furnace, microwave sintering furnace and other hot field insulation; For nuclear reactor thermal protection system; It can not only replace or reduce traditional refractories, but also greatly improve the effect of heat insulation and energy saving. According to different requirements can be processed into different shapes, sizes. |
