Abstract

Refractory ceramic prods. with open porosity are impregnated, to reduce infiltration by slags etc., with a thixotropic slurry based on finely-divided ceramic material, which can also contain C-contg. components e.g. resin and methyl cellulose to produce thixotropic properties. The slurry is liquefied by a mechanical vibrator or ultrasonic device and is introduced into the pores until a required degree of pore-filling is obtd., when the excitation is stopped. The prod. is heated to eliminate the liq. fraction and to crack the resin. ADVANTAGE - Simpler than pitch/tar impregnation with less environmental effects.
