Thallium Oxide Industrial Grade 99.9%

Thallium oxide include two kinds of oxides, thallium(I) oxide and thallium(III) oxide. Tl2O is  black powder, however Tl2O3 is brown or dark red powder. Thallous oxide is soluble in water, acid and alcohol. But thallium trioxide is not soluble in water and alkali.  Thallium trioxide dissolve in HCl and release chlorine, however release oxygen when dissolve in sulfuric acid.

Thallium(I) oxide is a kind of analytical reagent, which is also for optical glass and glass decoration.

Thallium(III) oxide is a kind of analytical reagent and catalyst. In electronic component production, it applies to prepare conductive paste for glass glaze potentiator.

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

CAS No.:13760-83-3 EINECS No.:237-356-3 Molecular Formula:ErF3 Molecular Weight:224.25
Density:7.814 Melting Point:1350℃ Boiling Point:2200℃ UN 3288 6.1/PG 3


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 YF3LaF3CeF3, 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.

Holmium Hydride Industrial Grade 99.9%

Neodymium trioxide mainly apply as colorant of glass and ceramic. It is also raw material for metal neodymium and strong magnetic Nd-Fe-B.

Adding 1.5%~2.5% nano neodymium oxide in magnesium alloys or aluminum alloys can enhance their high-temperature property, gas tightness and corrosion resistance. They are widely used as aerospace material.

Nano yttrium oxide aluminum garnet with doping nano neodymium oxide shots short wave laser beam. It widely apply to 10mm max thin material welding and cutting. In medical treatment, it can replace scalpel to do extraction or disinfect wound.

Neodymium trioxide can be additive for rubber goods.

Organic Germanium Industrial Grade 99%

Organic germanium includes synthetic organic germanium, natural organic GE and biological organic Ge. The synthetic one is carboxyethyl germanium sesquioxide that is Ge-132, spirogermanium, Furan germanium derivates and other antiviral, anti-inflammatory and anticancer organic Ge. It is compound that has wide pharmacologic action, but if over dose, it cause acalcerosis. Natural organic Ge is extracted from natural plants, which gets no toxic and side effect to human body. Biological organic Ge is planting germanium compounds into biological body, for example yeast, germ, macro fungi, vegetable and so on.  Ge-132 is short of (GeCH2CH3COOH)2O3

Organic Germanium

Ge-132 applies to functional health food, medicine, cosmetics and so on.
