Gold Powder Industrial Grade 99.9%

Gold powder is a kind of common precious metal, which is ultra fine particles. There are two production methods for ultra gold metal powder, thermal decomposition method and water solution reduction. The first one gets average particle size at 1~2μm. The second one gets average particle size at 0.5μm.

Gold Powder

Applications

Ultra fine Au powder is primary conducting material in excellent conductive paste as thin line gold paste, low temperature gold plasma, gold-palladium, gold-platinum-palladium and gold-silver-palladium.

Gold metal is as gilding material and raw material for gold wire in semiconductor industry.

Rhenium Rod Industrial Grade 99.9%

Rhenium metal is silvery rod, bar, stick, plate, sheet, foil, strip, coil and powder. It exists in soot from calcinator for molybdenite and copper ore, which is byproduct of refining molybdenum and copper. Ammonium perrhenate (NH4ReO4) and potassium perrhenate(KReO4) are the raw materials.  Its chemical properties are close to manganese and technetium.

Rhenium Metal 

Applications

Rhenium metal bar is mainly for nickel-rhenium alloys, which apply to manufacturing combustor, turbine blade and exhaust nozzle of jet engine.  These alloys contains 6% rhenium at highest.

Rhenium can enhance physical property of tungsten. W-Re alloys have better plasticity at low temperature and high-temperature stability is better too, which is easy to process and shape. The change increase with the amount of rhenium increase, so W-Re alloy contains 27% rhenium, which is also the solublity limit of rhenium in tungsten. The alloys can apply to X-ray sources and thermocouple

In chemical industry, rhenium metal powder can use as catalyst for dehydrogenation.  Rhenium metal powder is raw material for Pt-Re catalys that is for producing gasoline without lead and high octane.  It is for spectral analysis too.

Cerium Oxide Industrial Grade 99.9%

Cerium oxide is faint brown powder or faint yellow powder of CaF2 structure, which is hard to melt. Common oxides of cerium is cerium(III) oxide and cerium dioxide. Cerium dioxide is most important and typical oxide of cerium. Cerium(III) oxide has hexagonal structure of rare earth sesquioxide, which is mainly for catalysts.

Cerium Oxide

Applications

Cerium dioxide is mainly for polishing agent of lens. Rare earth polishing powder get wide applications in polishing of  camera, teletube, spectecles glasses, which is also for glass industry.

In glass industry, cerium dioxide combine with titanium dioxide, which make glass show yellow. it use for glass decolorizing, which have high temperature stability, low cost and nonabsorption of visible light and other advantages. Additionally cerium(IV) oxide add into glass for building and automotive glass, which can reduce light transmittance of ultraviolet light.

Ceric dioxide is raw material for production of rare earth luminescent material. It use as activating agent in luminescent material rare earth trichromatic phosphor of energy saving lamp and fluorescent powder of indicator light and radiation detector.

Cerium(IV) oxide is raw material in ceramic glaze and electronic industry as infiltration agent of piezoelectric ceramics. It is also as sensitizer of semiconductor material, advanced pigment and photosensitive glass, purifier of automobile exhaust.

Gold Hydroxide Industrial Grade 99%

Gold hydroxide is a brown precious metal compound, which tend to decompose when heating. It is insoluble in water and dilute acid, however soluble in strong acid, strong alkali and sodium cyanide solution. Gold(III) hydroxide is amphoteric,which is not stable and tend to decompose to AuO(OH) when heating to 100℃, Au2O3 when heating to 140-150℃. Potassium chloroaurate or gold chloride is the raw material.

Gold Hydroxide

Applications

Gold trihydroxide is mainly for preparing gold oxide, gold plating and ceramic pigments.

Nickel Nitride Industrial Grade 99%

Nickel nitride is dark gray powder, which is a kind of metal nitrides. Its hardness is very high, which can apply to refractory ceramics. Nickel powder is the raw material.

Nickel Nitride

Rhodium Iodide Industrial Grade 99%

Rhodium iodide is black crystal powder, which is a precious metal salt. It is stable at room temperature and room pressure. However when temperature reach 675℃, it starts to decompose. It is tend to absorb moisture in air and in soluble in water and most solutions. Rhodium powder is the raw material.

Rhodium Iodide

Applications

Rhodium(III) iodide is a chemical for experiment uses most of time.

Bismuth Sulfide Industrial Grade 99%

Bismuth sulfide is black or brown powder, which is minor metal sulfide and inorganic chemical compound. It is insoluble in water, but soluble in nitric acid and hydrochloric acid. Bismuth subnitrate pentahydrate or bismuth metal is the raw material.

Bismuth Sulfide

Applications

Bismuth(III) sulfide is photoelectric material, because B2S3 own property of environmentally friendly, photoconduction and non-linear optics response. Bismuth trisulfide is widely used in solar cell, photoelectric diode array and infrared spectroscopy.

Bi2S3 is also raw material for other bismuth compounds, easily cutting steel and micro-electronics.

Mercury Bromide Industrial Grade 99%

Mercury bromide is white crystal powder.  It gets other products as mercury(II) bromide, mercury dibromide, mercuric dibromide and so on. Yellow mercury oxide is the raw material.

Mercury Bromide

Applications

HgBr2 is for analytical reagent that test arsenic by Gutzeit method. It is also for medical industry.

Niobium Metal Industrial Grade 99.9%

Niobium metal is silvery white metal, which is ductile. It process into powder normally. However other forms are available too as chips, slugs, sheets, foils, granules, cylinders, ingot, wires and rods. Niobium metal is stable in air. Under high temperature, it compounds with sulfur, nitrogen and carbon. It alloy with titanium, zirconium, hafnium and tungsten easily. The chemical property of niobium is very close to tantalum. Although its corrosion resistance is not high as tantalum, but its price is lower and more common. So with low request situations, it replace tantalum like tank coating for chemical processing.

Niobium Metal

Applications

Niobium metal can absorb gas, which use as degasifier. It is also great superconductor at low temperature. Niobium is the third elements that is one of the II category superconductor after vanadium and technetium. The purity of niobium will affect its superconducting property.

Niobium metal apply to high-temperature alloys normally, for examples inconel 718, C-103, FS85, Cb129Y, Cb752 and Nb1Zr.  Inconel 718 is a kind of Ni-Nb alloy, which contain Ni 50%, Cr 18.6%, Fe 18.5%, Nb 5%, Mo 3.1%, Ti 0.9% and Al 0.4%. C-103 is a kind of niobium alloy, which contains 89% Nb, 10% Hf and 1% Ti.

Niobium powder is for welding electrode production normally. There are different kinds, FNb-1, FNb-2 and FNb-3.
