Europium Metal Purified 99.9%

Europium metal is steel grey metal of body-centered cubic lattice, which is soft and ductile. It is rare earth element, which is available with powder, foil, rod, piece, ingot, granule, slug, sputtering target. Eu react rapidly with oxygen and water. When heating to 150~180℃, it fires in air. Europium powder tend to ignite, which is most active among rare earth metals. There are two production method, reduction and distillation. Distilled Eu piece is dendritic with higher purity than reduced Eu metal.

Fluoroboric Acid

Fluoroboric acid (also spelt fluoboric acid) is the chemical compound with the formula HBF4. It is the conjugate acid of tetrafluoroborate. It is available commercially as a solution in water and other solvents such as diethyl ether. With a strength comparable to nitric acid, fluoroboric acid is a strong acid with a weakly coordinating, non-oxidizing conjugate base. fluoroboric acid mixtures and organic reagents are used as the electrolyte in the cathode treatment of the tin plating process. Similar processes of electrodeposition and electrolytic stripping are used to obtain specific metal alloys.

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.

Gallium Nitrate Industrial Grade 99%

Gallium nitrate is in hydrate compound normally, like nonahydrate, octahydrate and so on. They are both white crystal powder and tend to dissolve in water. Gallium metal, gallium hydroxide or gallium(III) oxide is the raw material for them. Gallium(III) nitrate hydrate turns into anhydrous compound by vacuum drying  and drying for 48 hour at 40℃.  Their storage should avoid reducing agent and oxidizable material. They melt at 65℃. It hydrolyzes once dissolving in water, which tend to dissolve in ethyl alcohol too.

Gallium Nitride Industrial Grade 99.99%

Gallium nitride is direct bandgap semiconductor, which is available in powder, wafer, monocrystal, ingot, piece, rod and so on. It is hexagonal crystal. GaN starts to decompose at 1050℃ (2GaN(s)=2Ga(g)+N2(g). It slowly volatilize in nitrogen or helium when temperature is 1000℃, which prove its stability at relatively high temperature. GaN does not decompose in cold water or hot water, dilute or concentrated hydrochloric acid, nitric acid and sulfuric acid, cold 40% HF. It is stable in cold concentrated alkali, but dissolve in alkali when heating. Gallium metalgallium phosphide or gallium arsenide  is the raw material.
