A lithium ion battery electrode formed by the pyrolysis of a silane polymer followed by introducing lithium ions. These electrodes can be used to form batteries with large capacities, low irreversible capacity, high density and good safety behavior.

Electrodes for lithium ion batteries using polysilanes

A method for preparing high density titanium diboride ceramic bodies in which titanium diboride powder is first mixed with a preceramic organosilicon polymer. The mixture is then molded and sintered under pressure or by a pressureless process.

A borosilicate containing coating is formed on an electronic substrate by applying a borosilazane polymer on the substrate and converting it to borosilicate by heating in an oxidizing environment. The resultant thick planarizing coatings are useful as protective coatings and dielectric inner layers.

Electrodes for lithium ion batteries using polysiloxanes

A method of crosslinking a silazane polymer having Si--H bonds in which the polymer is mixed with a crosslinker selected from alkenyl functional cyclosiloxanes and alkenyl functional cyclosilazanes and a crosslinking promoter and then heated to a temperature sufficient to crosslink the silazane polymer. The mixture of the silazane polymer, crosslinker and promoter is useful in the formation of ceramic matrix composites.

Crosslinkers for silazane polymers

Fiber reinforced ceramic matrix composites are prepared by coating refractory fibers having a interfacial coating thereon with a curable preceramic polymer having a char which contains greater than about 50% sealant oxide atoms followed by forming the coated fibers into the desired shape, curing the coated fibers to form a pre-preg, heating the pre-preg to form a composite and heating the composite in an oxidizing environment to form an in situ sealant oxide coating on the composite. The resultant composites have good oxidation resistance at high temperature as well as good strength and toughness.
