Method for producing refractory filaments |
摘要 |
A process for producing fibers of refractory material. In one embodiment, a dispersion of particles of refractory material is prepared first. The dispersion then is mixed with a carrier solution of a salt of cellulose xanthate to form a spin mix. Using general wet spinning techniques, a filament of regenerated cellulose is formed from the spin mix. The filament has the particles dispersed therein. At this point, the filament can be utilized as a mixture of cellulose and refractory material, or it can be heat treated. If heated, the filament is raised to sufficient temperatures and over sufficient durations to remove substantially all of the regenerated cellulose and to sinter the particles of refractory material to form a filament.
