Sodium Pyroantimonate is an inorganic salt compound of antimony, which is produced from antimony products such as antimony oxide through alkali and hydrogen peroxide. There are granular crystal and equiaxed crystal. It has good chemical stability.
Barium Carbonate(BaCO3) Powder 99.75% CAS 513-77-9

Barium Carbonate is manufactured from natural barium sulfate (barite). Barium Carbonate standard powder, fine powder, coarse powder and granular are all can be custom-made at UrbanMines.
Barium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%

Barium hydroxide, a chemical compound with the chemical formula Ba(OH)2, is white solid substance, soluble in water, the solution is called barite water, strong alkaline. Barium Hydroxide has another name, namely: caustic barite, barium hydrate. The monohydrate (x = 1), known as baryta or baryta-water, is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form. Barium Hydroxide Octahydrate, as a highly water insoluble crystalline Barium source, is an inorganic chemical compound that is one of the most dangerous chemicals used in the laboratory. Ba(OH)2.8H2O is a colorless crystal at room temperature. It has a density of 2.18g / cm3, water soluble and acid, toxic, can cause damage to the nervous system and digestive system. Ba(OH)2.8H2O is corrosive, may cause burns to eye and skin. It may cause digestive tract irratation if swallowed. Example Reactions: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
High purity Caesium nitrate or cesium nitrate(CsNO3) assay 99.9%

Cesium Nitrate is a highly water soluble crystalline Cesium source for uses compatible with nitrates and lower (acidic) pH.
Aluminum oxide alpha-phase 99.999% (metals basis)

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.
Boron Carbide

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.
