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

CAS No.: 7440-57-5 EINECS No.: 231-165-9 Molecular Formula: Au Molecular Weight: 196.97
Melting Point:1064.63℃ Boiling Point:2966℃ Density: 19.31  

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 

CAS No.:7440-15-5 EINECS No.: 231-124-5 Molecular Formula:Re Molecular Weight:186.207
Melting Point:3180℃ Boiling Point:5900℃ Density:21.04 UN 3178 4.1/PG 2

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.
