Formaldehyde Oxime

Formaldehyde oxime is a sensitive colorimetric reagent for manganese, copper and metals of the iron group.It constitutes a new and effective leaching agent for several types of ores, such as pyrolusite, malachite, heterogenite and deep-sea manganese nodules.

Formamide

Formamide is an amide derived from formic acid. It is a clear liquid which is miscible with water and has an ammonia-like odor. It is chemical feedstock for the manufacture of sulfa drugs, other pharmaceuticals, herbicides, pesticides and the manufacture of hydrocyanic acid. It has been used as a softener for paper and fiber. It is a solvent for many ionic compounds. It has also been used as a solvent for resins and plasticizers.Formamide is also a constituent of cryoprotectant vitrification mixtures used for cryopreservation of tissues and organs.Formamide is also used as an RNA stabiliser in gel electrophoresis by deionizing RNA. In capillary electrophoresis, it is used for stabilizing (single) strands of denatured DNA.Formamide, in its pure state, has been used as an alternative solvent for the electrostatic self-assembly of polymer nanofilms. It is also used for prehybridization and hybridization of biotinylated nucleic acid probes to nucleic acids fixed on membranes.

Gadolinium Metal Purified 99.9%

Gadolinium metal is rare earth, which is available in powder, ingot, granule, wire, sheet, foil, sputtering target and so on. It is silvery white metal and own ductility, which also own ferromagnetism and extraordinary superconductivity. Gd powder is soluble in dilute acid. It tends to oxidize in moisture air and turns dark. Gd ingot turns to white oxide after firing in air. It is relatively stable in dry air. There are two production methods, distillation method and reduction method. The distilled gadolinium piece is dendritic with higher purity than reduced one.

Gallic Acid

Gallic acid is a trihydroxybenzoic acid, a type of phenolic acid, a type of organic acid, found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. Gallic acid is found both free and as part of tannins. Salts and esters of gallic acid are termed 'gallates'. It is commonly used in the pharmaceutical industry. It is used as a standard for determining the phenol content of various analytes by the Folin-Ciocalteau assay; results are reported in gallic acid equivalents. Gallic acid can also be used as a starting material in the synthesis of the psychedelic alkaloid mescaline. Gallic acid seems to have anti-fungal and anti-viral properties. It acts as an antioxidant and helps to protect our cells against oxidative damage. Gallic acid is also used to treat albuminuria and diabetes. Some ointments to treat psoriasis and external haemorrhoids contain gallic acid.

Gallium Acetate Industrial Grade 99%

Gallium acetate is colorless or white crystalline powder or lump. It is a kind of important gallium salts. Normal compound is gallium acetate hydrate, however gallium acetate anhydrous is available. It is rare comparing to other gallium compounds as gallium oxide, gallium chloride, gallium nitride and gallium arsenide, because its uses are not specific.

Gallium Acetate

Synonyms: Gallium(III) actetate, Gallium Triacetate, Ga(C2H3O2)3, Gallium(3+) Acetate, G

Gallium Arsenide Industrial Grade 99.99%

Gallium arsenide is crystal of cubic crystal system, which is an important semiconductor material. It is available in pieces, ingots, rods, powders and wafers. It stable and don’t corrode by non-oxidizing acid under 600℃.GaAs could process into semi-insulating material that is triple electrical resistivity than silicon and germanium, which is for integrated circuit substrate and infrared detector. However it would decompose at high temperature, so the technique is complex to get ideal high purity monocrystal GaAs. Gallium metal and arsenic metal are the raw material.

Gallium Arsenide

Applications

Gallium monoarsenide is raw material for processing LCD, LD, FET, HEMT, HBT, MMIC and MIMIC. It is also raw material for high speed integrated circuit and solar battery.

Gallium Metal Industrial Grade 99.99%

Gallium metal is silvery white minor metal, which is liquid when temperature above 29℃, but solid when temperature under it. It is also soft even when solid.Ga is avaliable in liquid, solid, granule. Liquid gallium tends to undercool that mean it would’t solidify even temperature under 0℃. It slightly dissolve in mercury and form gallium amalgam. Liquid gallium can infiltrate glass, so it cannot use glass container to store.

Gallium Metal

Purity:99.99%, 99.999%, 99.99999%

Applications

Gallium metal mainly apply to produce semiconductor compounds as gallium arsenide, gallium nitride, gallium phosphide and so on. It is also dopant for semiconductor germanium, silicon.

99.99999% Ga is main raw material for gallium arsenide, gallium phosphide and gallium antimonide. Those are for LED and infrared device manufacturing. 8N Ga is mainly for preparing superlattice as gallium source of MBE, quantum well and other advanced semiconductor deveices.

High purity gallium can be as additive for permanent magnet material and other alloys. It is also raw material for high purity alloys.

Liquid gallium is raw material for gallium alloys as gallium-vanadium, gallium-lithium, gallium-zirconium and so on. Those alloys are as superconductor.  It is also essential raw material for low-melting alloys as bismuth alloys, zinc alloys, lead alloys and so on.
