Abstract: In the preparation of compact, crystalline and pore-free moldings from an oxide ceramic, amorphous oxide powders of beryllium, magnesium, aluminum, boron, zirconium, thorium or silicon or mixed oxides of silicon with these elements, in which some of the oxygen is replaced by bound nitrogen, are used as starting materials. These amorphous oxide powders containing bound nitrogen are compressed in a first stage at above the glass transition temperature but below the crystallization temperature to give a glassy molding, and the latter is then heated in a second stage to above the crystallization temperature. In the case of the individual oxides, from 5 to 30% of the oxygen are replaced by bound nitrogen, and in the case of the mixed oxides of silicon with these elements from 50 to 90% of the oxygen are replaced by bound nitrogen.

Abstract: An acrylic multifilamentary material possessing an internal structure which is particularly suited for thermal conversion to high strength carbon fibers is formed via a specifically defined combination of processing conditions. The acrylic polymer while in substantially homogeneous admixture with appropriate concentrations (as defined) of acetonitrile, C.sub.1 to C.sub.4 monohydroxy alkanol, and water is melt extruded and is drawn at a relatively low draw ratio which is substantially less than the maximum draw ratio achievable. This fibrous material which is capable of readily undergoing drawing is passed through a heat treatment zone wherein the evolution of residual acetonitrile, the monohydroxy alkanol and water takes place. The resulting fibrous material following such heat treatment is subjected to additional drawing to accomplish further orientation and internal structure modification and to produce a fibrous material of the appropriate denier for carbon fiber production.

Abstract: A method of increasing the absorbency of cellulosic fibers by treating the cellulosic fibers with an aqueous acid solution having a pH value of no more than 4. The treatment is carried out for a time sufficient to obtain the desired absorbency. Optionally, the aqueous acidic solution treatment can be preceded or succeeded by a hot water treatment to further increase the absorbency of the cellulosic fibers. The cellulosic fibers find particular application in nonwoven articles that require high absorbency, i.e., diapers, tampons, medical sponges, etc.
