Chengdu Beyond Chemical Co., Ltd.
Profile: Chengdu Beyond Chemical Co., Ltd. is engaged in the processing of rare earth (RE), molecular sieve, high purity metals & rare metals and gas. We have two share plants for rare earth processing and a new material center. We produce all kinds of rare earth products for industrial, research and artistic use. Our rare earth oxide is the most stable among various RE compounds; it is the fundamental raw material for making other compounds and is the basic raw material in the RE industry. The RE oxides are generally prepared by the ignition of corresponding hydroxide, oxalate, carbonate salt, nitrate salt, and soleplate salt in air. The RE oxides are insoluble in water and soluble in strong mineral acids; they absorb carbon dioxide from air to form carbonate salt. We offer rare earth metals. Their melt points and densities increase with the atomic number except europium and ytterbium, yet the hardness increases with the atomic number in spite of being soft. Although their tensile stresses are low, RE metals show fairly high stretching ability. The activities of the metals increase in sequence from Sc, Y, and La; however they decrease from La to Lu sequentially. The metals are liable to oxidize in the air, inert in cool water, but active in hot water & release hydrogen; they violently react with acids, but rather inactive to bases. Normally, RE metals are manufactured by electrolysis or by pyroreduction. The RE metals are rather effective reductants in metallurgical. These are used to prepare high performance magnets, fuel batteries, secondary cells, and functional non-ferrous materials.
