Vinylsilane

Vinylsilane is an organic chemical. It is a derivative of silane. It is used as a monomer for some copolymer plastics such as ethylene-vinylsilane and ethylene-vinyl acetate-vinylsilane. It is also used as a cross-linking agent during the manufacture of cross-linked polyethylene. The silane group is reactive, and in the presence of moisture, it forms cross-links as the material cures. Moisture-curable polymers are used as electrical insulation in some kinds of cables. Vinylsilane is also used as a coupling agent for treatment of glass fibers in order to form stronger bonds with resin and produce fiberglass with better mechanical properties.

Yttrium Oxide Purified 99.9%

Yttrium oxide is white to light yellow powder, which is a kind of rare earth oxides. It is insoluble in dilute acid, however nearly insoluble in water.

Yttrium Oxide

CAS No.:1314-36-9	EINECS No.:215-233-5	Molecular Formula:Y2O3	Molecular Weight:225.81
Melting Point:2439℃	Boiling Point:4300℃	Density:5.03	Flash Point:12℃

Applications

Yttrium(III) oxide granule can apply to thermal spray. For this application, it process into spherical large particle to get great flow ability. It should guarantee the whiteness too. Normally the production method is granulation.

Yttrium trioxide is important material for magnetic material for microwave and military project, which is also for optical glass. It can improve the refractive index of special glass and reduce dispersion index. So it is raw material for high brightness fluorescent powder for large-screen television and coating of other kinescope.

Yttria apply to produce thin film capacitor , special refractory material, high pressure mercury lamp, laser, memory parts and other magnetic bubble material. It is also for artificial laser crystal and superconductive material.

Yttrium(III) oxide powder is additive for lanthanum series glass and high temperature resistance and rediation resistance optical glass. It is also important additive for silicon nitride engineering ceramics, zirconium dioxide engineering ceramics, piezoelectric ceramics, photoelectric ceramics, semiconductor ceramics, thermistor ceramics, capacitor ceramics and other functional ceramics.

Yttria powder mainly apply to prepare new magnetic material yttrium iron garnet and solid laser material yttrium aluminum garnet (YAG). It is also a kind of hydrogen storage material.

ammonium metavanadate technical 99.5% Purified 99.5%

Ammonium Metavanadate

Ammonium metavanadate is a kind of inorganic chemical that is white crystalline powder. Its main applications cover chemical reagent, catalyst, drier and pigment. It dissolves in hot water and dilute ammonia water.

Ammonium Metavanadate

It tend to absorb moisture in air. When heating, ammonia and water would lose. Ammonium metavanadate dissolves in hot water and dilute ammonia water and faintly dissolve in cold water, however not in ethyl alcohol. It has some other product names like ammonium vanadate and ammonium vanadium oxide, which refer to same chemical.
