Praseodymium(III,IV) Oxide/Pr6O11 Powder 12037-29-5

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.

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.

UrbanMines produce and process pyrite products by flotation of primary ore, which is high quality ore crystal with high purity and very little impurity content. In addition, we mill the high quality pyrite ore into powder or other required size, so as to guarantee the purity of sulphur, few harmful impurity, demanded particle size and dryness.Pyrite Products are widely used as resulfurization for free cutting steel smelting and casting furnace charge, grinding wheel abrasive filler, soil conditioner, heavy metal waste water treatment absorbent, cored wires filling material, lithium battery cathode material and other industries. Ratification and favourable comment having got users globally.

Silicon Metal is commonly known as metallurgical grade silicon or metallic silicon because of its shiny metallic colour. In industry it is mainly used as an alumnium alloy or a semiconductor material. Silicon metal is also used in the chemical industry to produce siloxanes and silicones. It is considered to be a strategic raw material in many regions of the world. The economic and application significance of silicon metal on a global scale continues to grow. Part of the market demand for this raw material is met by a producer and distributor of silicon metal – UrbanMines.

Cerium Oxide, also known as Cerium(IV) Oxide or Cerium Dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.
