A silicon composite comprises silicon particles whose surface is at least partially coated with a silicon carbide layer. It is prepared by subjecting a silicon powder to thermal CVD with an organic hydrocarbon gas and/or vapor at 900-1,400&#xb0; C., and heating the powder for removing an excess free carbon layer from the surface through oxidative decomposition.

Silicon composite, making method, and non-aqueous electrolyte secondary cell negative electrode material

Silicon composite particles are prepared by sintering primary fine particles of silicon, silicon alloy or silicon oxide together with an organosilicon compound. Sintering of the organosilicon compound results in a silicon-base inorganic compound which serves as a binder. Each particle has the structure that silicon or silicon alloy fine particles are dispersed in the silicon-base inorganic compound binder, and voids are present within the particle.

Silicon composite particles, preparation thereof, and negative electrode material for non-aqueous electrolyte secondary cell

A non-aqueous electrolyte secondary battery negative electrode material is provided wherein a negative electrode active material containing a lithium ion-occluding and releasing material which has been treated with an organosilicon base surface treating agent is surface coated with a conductive coating. Using the negative electrode material, a lithium ion secondary battery having a high capacity and improved cycle performance is obtainable.

Non-aqueous electrolyte secondary battery negative electrode material, making method, and lithium ion secondary battery

A conductive silicon composite in which particles of the structure that silicon crystallites are dispersed in silicon dioxide are coated on their surfaces with carbon affords satisfactory cycle performance when used as the negative electrode material in a non-aqueous electrolyte secondary cell.

Conductive silicon composite, preparation thereof, and negative electrode material for non-aqueous electrolyte secondary cell

A lithium ion secondary cell having a high capacity, improved first charge/discharge efficiency and improved cycle performance is obtainable using as the negative electrode material a lithium-containing silicon oxide powder having the formula: SiLiOwherein x and y are 0&#x3c;x&#x3c;1.0 and 0&#x3c;y&#x3c;1.5, with the lithium being fused and partially crystallized.

Lithium-containing silicon oxide powder and making method

An air bag coating composition is obtained by emulsifying (A) an organopolysiloxane containing at least two alkenyl groups each attached to a silicon atom, (B) an organohydrogenpolysiloxane containing at least three hydrogen atoms each attached to a silicon atom, and (C) a curing catalyst in water in the presence of an emulsifier to form an aqueous silicone emulsion. The composition cures into a coating which firmly adheres to an air bag base fabric and provides a tack-free surface.

Air bag coating composition and air bag

An air bag coating composition predominantly comprising an organopolysiloxane having a degree of polymerization of 1,000 to 10,000 and a molecular weight distribution index (Mw/Mn) of less than 5 is provided. The composition is applied and cured to an air bag base fabric without strike-through.

Air bag coating composition, air bag and preparation thereof

A coating composition for the air bag which comprises

Coating composition for air bags and air bag

An air bag coating composition is provided in the form of an aqueous silicone emulsion composition comprising (A) an aqueous emulsion of a hydroxyl-containing organopolysiloxane, (B) a reaction product of an amino functional silane or a hydrolyzate thereof with an acid anhydride, an epoxy-functional silane or a hydrolyzate thereof, or an organosilane having an isocyanate radical and a hydrolyzable radical in a molecule or a hydrolyzate thereof, (C) colloidal silica, and (D) a curing catalyst. The composition is applied and cured to an air bag base fabric to form a tack-free, crack resistant coating thereon.

A silicone rubber composition comprising an organopolysiloxane and a curing agent is improved by adding a foaming agent in an amount of 0.1 to 10 parts by weight per 100 parts by weight of the organopolysiloxane. The composition is heat curable into silicone rubber films or coatings which are substantially unfoamed and tack-free on a surface.

Silicone rubber film - forming composition and silicone rubber film

An organopolysiloxane composition comprising (A) an organopolysiloxane having at least two aliphatic unsaturated radicals attached to different silicon atoms per molecule, (B) an organic silicon compound having at least two .tbd.SiH bond per molecule, and (C) a platinum catalyst is improved in curing behavior including pot life and curing time as well as release properties by adding thereto (D) an addition reaction controlling agent in the form of an isothiocyanate such as allyl, ethyl and phenyl isithiocyanates.

Organopolysiloxane compositions and cured products thereof

A solvent-free releasing silicone composition for rendering surfaces non-adherent which gives a cured film having desirable slip factor, toughness, and high-speed peel characteristics without sacrificing its inherenty merits such as curability, uniformity in peel resistance, and the residual adhesive strength employs a diorganovinylpolysiloxane having trivinylsilyloxy as one end group and either a vinyldimethylsilyl or trimethylsilyl group as the other end group.

Silicone composition for rendering surfaces non-adherent

A releasing silicone composition comprising three ingredients including an organopolysiloxane having at least two specific organosiloxy units having an alkenyl group, a methylhydrogenpolysiloxane material, and a platinum catalyst.
