Bismuth is a silvery-red, brittle metal that is commonly found in the medical, cosmetic, and defense industries. UrbanMines takes full advantage of High Purity (over 4N) Bismuth Metal Ingot’s intelligence.
Lithium Bromide (LiBr)

Lithium Bromide (LiBr), a hygroscopic compound composed of lithium and bromine, is widely utilized in industrial and chemical applications due to its unique physicochemical properties. It is synthesized via reactions such as treating lithium carbonate with hydrobromic acid or reacting lithium hydroxide with bromine, yielding crystalline hydrates distinct from other alkali metal bromides.
Trimethylaluminum(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.
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.
