    Abstract: The present invention provides a transition metal/polymer matrix composite material which has durable, wear and corrosion resistant and friction reducing characteristics which can be used in a powder or liquid form, or, which can be bonded to a desired surface at ambient temperature. The specific components are transition metal dichalcogenides (TMDs) including disulfides, diselenides and ditellurides of Ti, Zr, Hf, V, Nb, Cr, Mo, and W, and polymers including polytetrafuoroethylene (PTFE), hexafluoropropylene, perfluoroalkoxyvinyl ether, ethylenetetrafluoroethylene polymer, polyvinylidene fluoride and ethylenechlorotrifluoroethylene polymer. This invention brings together the unique properties of organic chemistry (PTFE) and inorganic chemistry (TMD's) which creates a synergistic interaction optimizing the friction reducing properties of PTFE with similar friction reducing properties of select TMD's and the TMD's additional wear-resistance and natural tendency for forming a tenacious physical bond at a molecular level. The invention comprises a mixture of PTFE and TMDs (particularly tungsten disulfide and molybdenum disulfide) which can be applied to a substrate through a variety of mechanisms and manners to form a lubricious and wear-resistant layer ranging from 0.5 micron to 60 microns thick.

    Abstract: A curable silicone composition which can cure using hydrosilylation, comprising an aluminum oxide powder and/or silica powder, the powders each consisting of substantially spherical particles with an average particle diameter of 50 .mu.m or below and an elongation of from 1.0 to 1.4 and being such that the respective amounts of alkali metal ions and halogen ions are extracted with 50 ml of water from 5 g of the powder at 121.degree. C. for 20 hours are not more than 10 ppm, wherein the amount of the component (D) is from 25 to 90% by weight based on the composition, and the ratio of the amount of hydrosilyl groups contained in the components (A) and (B) to the amount of alkenyl groups contained in the components (A) and (B) is in the range from 0.5/1 to 1.5/1. When the composition is used as a protective material or encapsulating material for devices such as ICs, generated heat can be dissipated efficiently and the devices are not be broken by abrasion. There are no fears of causing corrosion of the devices.
