    Abstract: A thermoplastic molding composition comprising (1) a polyamide, (2) polytetrafluoroethylene and (3) an inert filler selected from the group consisting of silica and magnesium oxide is provided. The composition can be pressed and sintered, injection molded, compression molded, extruded or readily applied to a substrate by spraying, dipping or painting. It is self-lubricating and highly resistant to creep and wear, and is especially adapted for use as self-lubricating bearing surfaces or elements such as machine tool bed ways, gears, rollers, cams and the like.

    Abstract: SOLID, ELECTRICALLY CONDUCTIVE ARTICLES COMPOSED OF A MIXTURE OF THE DIBORIDE AND THE NITRIDE OF TITANIUM AND/OR ZIRCONIUM ARE DESCRIBED. THESE ARTICLES ARE PREPARED BY HOT-PRESSING FINELY DIVIDED PARTICLES OF THE METAL WITH BORON NITRIDE, THE MIXTURE OPTIONALLY CONTAINING ELEMENTAL BORON AND MOLYBDENUM DISILICIDE, AT A TEMPERATURE OF AT LEAST 2000*C. UNDER PRESSURE OF FROM 2000 TO 15,000 P.S.I. UNDER AN INERT ATMOSPHERE. THE ARTICLES OF THE INVENTION ARE USEFUL AS CATHODE CONNECTOR BARS FOR THE ELECTROLYTIC CELL USED IN PREPARING ALUMINUM. IN ADDITION THEIR REFRACTORY AND MECHANICAL STRENGTH PROPERTIES MAKE THEM SUITABLE FOR MANY APPLICATIONS IN AND AROUND INDUSTRIAL FURNACES, ROCKET AND JET ENGINES, AND THE LIKE.
