Chromium Pieces Industrial Grade 99.9%

Chromium pieces are mainly for smelting. Two purity are available, 99% and 99.8%. It could be in other shapes too as lumps, ingots, sheets, rods, granules, wires and so on. Chromium is silvery white metal, which is hard and brittle. It is inactive metal and stable to oxygen and moisture at room temperature. Chromium pieces is of irregular small lumps. 99.99% and 99.95% Cr is product by hydrogen reduction process. 99.5%-99.8% Cr is product by carbon reduction process.

Chromium Pieces

Applications

Chromium metal is mainly for hard alloys, diamond tools, welding materials, stainless steel, targets, vacuuming coating, thermal spraying and ceramics.

Chrome ingots apply to tough malleable steel, stainless steel and acid proof alloy. Pure chromium can apply to electroplate.  It is raw material for high temperature alloys, electro-resistance alloys and precision alloys. It can improve hardness and corrosion resistance in alloy steels. In non-ferrous alloys, chromium lumps can improve high-temperature strength, fracture resistance, corrosion resistance and antioxidant.

Chromium Powder Industrial Grade 99.9%

Chromium powder is dark gray fine particle, which have strongest hardness. It can protect metal when coating.

Chromium Powder

Applications

Pure chrome powder is for electroplating.

Di Ammonium Phosphate LAB GRADE > 99 %

Di Ammonium Phosphate [also known as Di Ammonium Hydrogen Phosphate or Ammonium Phosphate Dibasic] is manufactured by the reaction of Ammonia Gas and Phosphoric Acid. DAP is used in a wide range of industries such as Food & Beverages, Agriculture, Animal Feed Industry etc.

Erbium Fluoride Industrial Grade 99.5%

Erbium fluoride is roseal crystal, which is rare earth metal fluoride. It is insoluble in water and dilute acid and hard to dissolve in hydrofluoric acid, but dissolve in sulfuric acid. Erbium(III) fluoride is stable at room temperature and pressure. ErF3 use erbium chloride or erbium nitrate as raw material.

Erbium Fluoride

Purity: Er/RE 99.5% 2N5

Applications

Erbium trifluoridie uses in optical coating, optical fiber dopant, laser crystal, monocrystal raw material, laser amplifer, catalytic addictives and so on.

Erbium(III) fluoride film play important roles in space optics, photo-communication, spectrograph and other large optical systems. In far infrared region, rare earth fluorides as YF3, LaF3, CeF3, HfF4, NdF3 were reported with their optical constant, but rare for ErF3. ErF3 is heavy rare earth fluoride that belong to lanthanum series. In files of recent ten years, reports about erbium(III) fluoride’s infrared ray optical constant is few. Most of researches focus on infrared transmittance glass containing ErF3.

Gallium Sulfate Industrial Grade 99.9%

Gallium Sulfate Anhydrous and Hydrate

Hafnium Sticks Industrial Grade 99.9%

Hafnium metal is a kind of transition metal of silver gray metallic, which is in form of powder, rod, ingot, bar, target , foil, wire and piece. It exists accompany with zirconium normally. There are two crystal structures of hafnium, one is hexagonal close packing (α-type at less than 1300℃, the other is body-centered cubic (β-type). Hafnium rod is ductile metal, however it turn hard and brittle when impurities exist. It is stable in air and turn dark when igniting. Hafnium wire can ignite by match. Its property is close to zirconium. It is soluble in  aqua regia and hydrofluoric acid, but doesn’t dissolve in water, dilute acid or alkali. Hafnium alloy (Ta4HfC5) is the material of highest melting point that is about 4215℃ at present.

Hafnium metal reacts with air and forms oxide layer protection. At temperature 500~750℃, the oxide layer protection lose its effect and compouds with oxygen and nitrogen ,which turns out oxides and nitrides. At temperature >800℃, Hafnium powder rapidly oxidize and forms HfO2. At temperature 1000℃, it reacts with CO and forms oxides and carbides.

Hafnium metal powder can be as cathode of X-ray tube. Hafnium alloys with tungsten or molybdenum can be as electrode of high voltage discharge tube. Hf-Ta alloy is raw material for chisel tool steel and resistance material. Hf-10% Nb alloy could be as nozzle of moon shuttle. Hf-2% TaWu alloy could be as protection coating of spacecraft.

Hafnium powder can be thruster of rocket. it is a kind of additive for hydraulic oil, which prevent the volatilization when high-risk operations. It has strong resistance to volatile. It works in industrial hydraulic oil and medical hydraulic oil.

Hafnium rod owns good welding property, processability, high temperature resistance and corrosion resistance. So it is an important raw material in atomic enery industry. Thermal neutron capturing area of Hafnium rod is big, which is ideal neutron absorber. It could be used as control rod and protector in atomic reactor.

In chemical, hafnium powder can act as getter for many inflation systems. Hafnium getter could remove existed oxygen, nitrogen and other unnecessary gases. Additionaly Hafnium powder has strong  volatility resistance.
