Manganese(II) Chloride, MnCl2 is the dichloride salt of manganese. As inorganic chemical existting in the anhydrous form, the most common form is dihydrate (MnCl2·2H2O) and tetrahydrate (MnCl2·4H2O). Just as many Mn(II) species, these salts are pink.
Terbium(III,IV) Oxide

Terbium(III,IV) Oxide, occasionally called tetraterbium heptaoxide, has the formula Tb4O7, is a highly insoluble thermally stable Terbium source.Tb4O7 is one of the main commercial terbium compounds, and the only such product containing at least some Tb(IV) (terbium in the +4 oxidation state), along with the more stable Tb(III). It is produced by heating the metal oxalate, and it is used in the preparation of other terbium compounds. Terbium forms three other major oxides: Tb2O3, TbO2, and Tb6O11.
Trimethylalumane(TMAI)

Trimethylaluminum (TMAI) is a critical raw material for the production of other metal-organic sources utilized in atomic layer deposition (ALD) and chemical vapor deposition (CVD) processes.

Trimethylaluminum represents one of the simplest organoaluminum compounds. Although its name suggests a monomeric structure, it actually has the formula Al2(CH3)6 (abbreviated as Al2Me6 or TMAI), existing as a dimer. This colorless liquid is pyrophoric and plays an industrially significant role, closely related to triethylaluminum.

UrbanMines ranks among the leading suppliers of Trimethylaluminum (TMAI) in China. Leveraging our advanced production techniques, we offer TMAI with varying levels of purity, tailored specifically for applications in the semiconductor, solar cell, and LED industries.
Boron Powder

Boron, a chemical element with the symbol B and atomic number 5, is a black/brown hard solid amorphous powder. It is highly reactive and soluble in concentrated nitric and sulfuric acids but insoluble in water, alcohol and ether. It has a high neutro absorption capacity.
UrbanMines specializes in producing high purity Boron Powder with the smallest possible average grain sizes. Our standard powder particle sizes average in the range of – 300 mesh, 1 microns and 50~80nm. We can also provide many materials in the nanoscale range. Other shapes are available by request.
Erbium Oxide

Erbium(III) Oxide, is synthesized from the lanthanide metal erbium. Erbium oxide is a light pink powder in appearance. It is insoluble in water, but soluble in mineral acids. Er2O3 is hygroscopic and will readily absorb moisture and CO2 from the atmosphere. It is a highly insoluble thermally stable Erbium source suitable for glass, optical, and ceramic applications. Erbium Oxide can be also used as a flammable neutron poison for nuclear fuel.
Manganese(ll,lll) Oxide

Manganese(II,III) oxide is a highly insoluble thermally stable Manganese source, which the chemical compound with formula Mn3O4. As a transition metal oxide, Trimanganese tetraoxide Mn3O can be described as MnO.Mn2O3, which includes two oxidation stages of Mn2+ and Mn3+. It can be used for a variety of applications such as catalysis, electrochromic devices, and other energy storage applications. It is also suitable for glass, optic and ceramic applications.
Tellurium Micron/Nano Powder Purity 99.95 % Size 325 mesh

Tellurium is a silver-gray element, somewhere between metals and non-metals. Tellurium Powder is a non-metallic element recovered as a by-product of electrolytic copper refining. It is a fine gray powder made of antimony ingot by vacuum ball grinding technology.

Tellurium, with atomic number 52, is burned in the air with a blue flame to produce tellurium dioxide, which can react with halogen, but not with sulfur or selenium. Tellurium is soluble in sulfuric acid, nitric acid, potassium hydroxide solution. Tellurium for easy heat transfer and electrical conduction. Tellurium has the strongest metalality of all non-metallic companions.

UrbanMines produces pure tellurium with purity range from 99.9% to 99.999%, which can also be made into irregular block tellurium with stable trace elements and reliable quality.The tellurium products of tellurium include tellurium ingots, tellurium blocks, tellurium particles, tellurium powder and tellurium dioxide, purity range from 99.9% to 99.9999%, and can also be customized to purity and particle size according to customer needs.
Barium Acetate 99.5% Cas 543-80-6

Barium acetate is the salt of barium(II) and acetic acid with a chemical formula Ba(C2H3O2)2. It is a white powder that is highly soluble in water, and decomposes to Barium oxide on heating. Barium acetate has a role as a mordant and a catalyst. Acetates are excellent precursors for production of ultra high purity compounds, catalysts, and nanoscale materials.
Niobium Powder

Niobium Powder (CAS No. 7440-03-1) is light grey with a high melting point and anti-corrosion. It takes on a bluish tint when exposed to air at room temperatures for extended periods. Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties it resembles tantalum. The metal’s oxidation in air commences at 200°C. Niobium, when used in alloying, improves strength. Its superconductive properties are enhanced when combined with zirconium. Niobium micron powder finds itself in various applications such as electronics, alloy-making, and medical due to its desirable chemical, electrical, and mechanical properties.
