Bismuth Trioxide (Bi2O3) is the prevalent commercial oxide of bismuth. As a precursor to the preparation of other compounds of bismuth, bismuth trioxide has specialized uses in optical glass, flame-retardant paper, and, increasingly, in glaze formulations where it substitutes for lead oxides.

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.

Boron Carbide (B4C), also known as black diamond, with a Vickers hardness of >30 GPa, is the third hardest material after diamond and cubic boron nitride. Boron carbide has high cross section for absorption of neutrons (i.e. good shielding properties against neutrons), stability to ionizing radiation and most chemicals. It is a suitable material for many high performance applications due to its attractive combination of properties. Its outstanding hardness makes it a suitable abrasive powder for lapping, polishing and water jet cutting of metals and ceramics. Boron Carbide is an essential material with lightweight and great mechanical strength. UrbanMines’ products have high purity and competitive prices. We also has much experience in supplying a range of B4C products. Hope we can offer helpful advice and give you a better understanding of boron carbide and its various uses.

Cesium Carbonate is a powerful inorganic base widely used in organic synthesis. It is a potential chemo selective catalyst for the reduction of aldehydes and ketones to alcohols.

Cesium Chloride is the inorganic chloride salt of caesium, which has a role as a phase-transfer catalyst and a vasoconstrictor agent. Caesium chloride is an inorganic chloride and a caesium molecular entity.

UrbanMines specializes in producing high purity Cobalt Powder with the smallest possible average grain sizes, which are useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Our standard powder particle sizes average in the range of ≤2.5μm, and ≤0.5μm.

Cobalt (II) Oxide appears as olive-green to red crystals, or greyish or black powder. Cobalt (II) Oxide is used extensively in the ceramics industry as an additive to create blue colored glazes and enamels as well as in the chemical industry for producing cobalt(II) salts.

Cobaltous Chloride (CoCl2∙6H2O in commercial form), a pink solid that changes to blue as it dehydrates, is utilized in catalyst preparation and as an indicator of humidity.
