Lithium carbonate(Li2CO3) 554-13-2

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.

High purity (over 98.5%) Beryllium Metal Beads are in small density, large rigidity and high thermal capacity, which has excellent performance in the process.

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.

Lithium Hydroxide is an inorganic compound with the formula LiOH.The overall chemical properties of LiOH are relatively mild and somewhat similar to alkaline earth hydroxides than other alkaline hydroxides.  Lithium hydroxide, solution appears as a clear to water-white liquid which may have a pungent odor. Contact may cause severe irritation to skin, eyes, and mucous membranes.  It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide. 

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.   LiBr exhibits exceptional solubility in water, alcohol, and ether, with concentrated aqueous solutions displaying low water vapor pressures. This property, combined with its high hygroscopicity, makes it an efficient desiccant and liquid sorbent, particularly in absorption refrigeration and air-conditioning systems. Additionally, its ability to dissolve polar organic compounds like cellulose expands its utility in specialized chemical processes, including catalytic dehydrohalogenation for olefin synthesis.   In water treatment and crystal growth applications, LiBr’s solubility and ultra-high purity forms (submicron/nanopowders) are advantageous. The bromide ion can be detected in aqueous solutions using carbon disulfide and chlorine. However, handling requires caution: LiBr generates significant heat upon dissolution (due to negative enthalpy of solution) and poses hazards as a mildly corrosive and psychoactive substance.   UrbanMines supplies LiBr in various grades (Mil Spec, ACS, Pharmaceutical, etc.), packaging options, and purities, adhering to ASTM, USP, and EP/BP standards. Technical support, safety data (MSDS), and unit conversion tools are provided to ensure safe and optimized application across industries.

Antimony is a bluish-white brittle metal, which has low thermal and electrical conductivity. Antimony Ingots have high corrosion and oxidation resistance and are ideal for conducting various chemical processes.

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.
