Cerium Oxide (Cerium Dioxide) CeO2 1306-38-3 12014-56-1

Erbium oxide (Er₂O₃) is a pink powdered rare earth oxide with stable chemical properties, excellent high-temperature resistance and thermal stability. Slightly hygroscopic, it should be stored in a sealed container. It is insoluble in water and slightly soluble in acids.

Aluminum Oxide (Al2O3) is a white or nearly colourless crystalline substance, and a chemical compound of aluminum and oxygen. It is made from bauxite and commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Al2O3 is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.

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 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.

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.
