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.

Gadolinium Metal

Purity: Gd/REM 99.9% 3N

Particle size: -100mesh, -200mesh

Applications

Gadolinium metal foil mainly applies to prepare magneto-optic material and magnetic refrigerant material. It also acts as neutron absorber material in atomic reactor. Gadolinium metal powder is catalyst in chemical reaction. It is raw material for fluorescent powder of microwave technology and colored TV.

Gold Oxide Industrial Grade 99%

Gold oxide is black powder, which is a precious metal oxide. It is stablest gold oxides, which is insoluble in water, however soluble in hydrochloric acid, concentrated nitric acid and sodium cyanide solution. Gold(III) oxide is sensitive to light and decompose gradually, so the container is brown bottle under low temperature. Gold hydroxide is the raw material.

Gold Oxide

Applications

Auric oxide is mainly for gold plating and pigment for ceramics.

Lanthanum Foils LAB GRADE 99.9%

lanthanum foils rare earth metal sheets

La REM 99.9%

sputtering target, evaporation coating material, vacuum coating material

Magnesium Sulfide LAB GRADE 99%

Magnesium sulfide is colorless to brown crystal powder, which is sulfide of magnesium. It is of sodium chloride type structure and the chemical property is similar to other  ionic type sulfide compounds as sodium sulfide, barium sulfide and calcium sulfide. Magnesium metal and pure sulfur are the raw materials.  It dissolve in diluted hydrochloric acid, however MgS crystal react with water slowly.

Magnesium Sulfide

Applications

Magnesium sulphide can apply to do desulfurization for iron and steel and making fluorescent powder.  It can apply as a semiconductor with wide band gap.

Neodymium Sulfide LAB GRADE 99%

neodymium sulfide reddish brown cubic crystal orthorhombic crystal

n-type semiconductor material

Tris(hydroxymethyl)aminomethane

Tris(hydroxymethyl)aminomethane is extensively used in biochemistry and molecular biology as a component of buffer solutions, such as in TAE and TBE buffer, especially for solutions of nucleic acids. It contains a primary amine and thus undergoes the reactions associated with typical amines. It is also used as a primary standard to standardize acid solutions for chemical analysis.
