Arsenic Trioxide Industrial Grade 99.99%

Arsenic trioxide is odorless white powder, which is most marketable arsenic compound and main start raw material for arsenic chemicals. It is faintly soluble in water and soluble in acid and alkali. The highest purity is 99.999%.

Arsenic Trioxide

CAS No.:1327-53-3 EINECS No.:215-481-4 Molecular Formula:As2O3 Molecular Weight:197.84
Melting Point:313℃ Boiling Point:465℃ Density:4.2 UN 1561

Applications

Arsenia is mainly for refining of arsenic metal, which is also raw material for melting arsenic alloys and produce semiconductors. It uses as clarifying agent and decolorising agent in glass industry, which improve transparency of glass products.

In farming, arsenic(III) oxide apply as sanitizer and rust remover for insect disease prevention, which is also raw material for insecticidal pesticide containing arsenic.

Arsenic oxide use to produce coating and dyestuff. It is also kind of chemical reagent as standard reagent, reducing agent and absorbent of chlorine.

As2O3 get applications in desulfuration, anticorrosion of wood, antiscale of boiler, ceramic,  enamel, lether preservative and medicine.

Cerium Hexaboride Industrial Grade 99.9%

Cerium hexaboride is dark gray powder, which is a rare earth boride. It has relatively low work function that is about 2.5 eV, so decide it is cathode material of extremely high electron emissivity. It is also a refractory ceramic material. Cerium boride is stable in vacuum. CeB6 is dense Kondo-like behaviour. It has better resistance to carbon pollution and longer life than lanthanum boride cathode. Its working temperature is 1450℃ usually.  CeB6 like LaB6 will slowly evaporate at working period. Cerium boride is insoluble in water.

Cerium Hexaboride

Purity: Ce/RE 99.9% 3N

Particle size: -20~500mesh

CAS No.:12008-02-5 Molecular Formula:CeBor B6Ce-2 Molecular Weight:204.976 EC Number:234-526-9
Melting Point:2552℃      

Applications

Cerium hexaboride mainly uses for a coating of hot cathodes, or cerium boride crystal makes up hot cathodes directly. CeB6 and LaB6are usually used for some coating of high current hot cathode with heavy current. CeB6 cathode has lower evaporation rate than lanthanum boride below 1700K, but they get to same and even higher evaporation rate at 1850K. It has 50% higher life than LaB6 due that it has better resistance to carbon pollution. The brightness of boride cathode  is 10 times than tungsten cathode and at same time its life is 10-15 times higher than tungsten cathode. Their common uses are electron microscope, microwave tube, electron beam lithography, electron beam welding, X-ray tube and free electron laser.

Gallium Arsenide Industrial Grade 99.99%

Gallium arsenide is crystal of cubic crystal system, which is an important semiconductor material. It is available in pieces, ingots, rods, powders and wafers. It stable and don’t corrode by non-oxidizing acid under 600℃.GaAs could process into semi-insulating material that is triple electrical resistivity than silicon and germanium, which is for integrated circuit substrate and infrared detector. However it would decompose at high temperature, so the technique is complex to get ideal high purity monocrystal GaAs. Gallium metal and arsenic metal are the raw material.

Melting Point:1238℃ Density:6.307 UN 1557 6.1/PG 2 Purity: 99.999%

Applications

Gallium monoarsenide is raw material for processing LCD, LD, FET, HEMT, HBT, MMIC and MIMIC. It is also raw material for high speed integrated circuit and solar battery.

Gallium Selenide Industrial Grade 99.99%

Gallium selenide includes gallium(III) selenide and gallium(II) selenide, which are minor metalselenides. Ga2Se3 is reddish black brittle hard lumps, ingot piece or powder, however GaSe is dark brown crystal, which are both photoelectric material. GaSe is layer structure semiconductor as GaS. With temperature decrease, Max value of its photoelectric effect move to shortwave end. Selenium metal and gallium metal are raw material for both Ga2Se3 and GaSe.
