Terbium Metal Purified 99.9%

Terbium metal is silver gray metal, which is a kind of rare earth metal. There are two production method, distillation and reduction. Distilled terbium is dendritic with metal luster. Reduced terbium is dark gray without metal luster. Distillation method get higher purity than reduction method. It tend to corrode by air when heating, but extremely slow at room temperature.  Its main compounds include terbium trioxide, terbium dioxide, terbium fluoride, terbium chloride and other terbium(IV) salts. Terbium can process into foil, sheet, wire, rod, powder and sputtering target. Tb ingot is of REM 99.99% by reduction method and distillation method. The distilled terbium piece is dendritic with higher purity than reduced Tb. Tb powder is of REM 99.9% and particle size -100mesh and -200mesh.

Applications

Distilled terbium metal apply to make high-temperature fuel cell and laser material. Calcium fluoride, calcium tungstate, strontium molybdate doped with terbium can apply to make solid state device.

Terbium magneto-optic material has bulk production, which is a kind of magneto-optic storage material. Magneto-optic disc of Tb-Fe non-crystal film can be as computer memory element, which increase storage by 10-15times.

Faraday rotatory glass containing terbium is key material in processing rotator, isolator and circulator that widely used in laser technology. Especially TerFenol. Terfenol is new material that found in 70s. Half of the alloy are terbium and dysprosium. Sometime adding holmium. The balance is iron. Tb-Dy-Ir mainly apply to sonar initially, but now it gets more and more applications as fuel injection system, liquid valve control, wing adjuster, special loudspeaker and so on.

Terbium metal can apply to do nondestructive inspection for welding spot of ships and pipeline.

Tetraethylammonium Hydroxide

Tetraethylammonium hydroxide is used as a phase transfer catalyst for electronic industy.

Tetramethylammonium Chloride

Tetramethylammonium chloride is a quaternary ammonium salt. It has few applications, unlike quaternary ammonium salts that feature more longer alkyl substituents. It is used in organic synthesis for methylation and occasionally as a precipitating agent. In low concentrations, it is used with polymerase chain reactions to increase yield and specificity.

Tetramethylthiuram disulfide

Tetramethylthiuram disulfide compound is used as a fungicide, seed disinfectant, bactericide, animal repellent, insecticide. It is used as a primary and secondary accelerator or as a sulfur donor (vulcanizing agent) in most sulfur-cured elastomers in rubber industry. It is also used in the treatments of chronic alcoholism with cause of acetaldehyde, a breakdown product of alcohol, to accumulate in the blood. It is a peptizing agent in sulfur-modified polychloroprenes. It is used in soaps and rodent repellents and as a nut, fruit and mushroom disinfectant.

Tetraphenylcyclopentadienone

Tetraphenylcyclopentadienone is an organic compound. Because of its highly conjugated nature, it can be analyzed in the UV spectrum. It has a propeller shape in its 3D conformation. The four phenyl rings are rotated out of the plane compared to the central ring because of steric repulsion with each other. These rings reduce the reactivity of the cyclopentadienone core by sterically blocking other reactants from getting close enough to it. It is used as the diene in the Diels-Alder synthesis of 1,2,3,4-tetraphenylnaphthalene with benzyne as the dienophile. It may also be used to prepare hexaphenylbenzene by reaction with diphenylacetylene in the Diels-Alder reaction.

VCM (Vinyl Chloride Monomer)

Vinyl chloride is a colorless compound and is important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). At ambient pressure and temperature, vinyl chloride is a gas with a sickly sweet odor. It is highly toxic, flammable and carcinogenic.

ZEOCHEM Molecular Sieves 13X

ZEOCHEM Molecular Sieves 13X is the sodium form of the type X crystal and has a larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 9 Angstrom (0.9 nm) and exclude those larger.
