Lanthanum Boride Polycrystalline LaB6 CAS 12008-21-8 For High-power Electronic Tube Material

Lanthanum hexaboride (LaB6), referred to as lanthanum boride, is a purple powdery rare earth boride, insoluble in water and hydrochloric acid. It has the characteristics of high melting point (2715℃), high strength and high stability, and is an important field emission material. Lanthanum hexaboride series products mainly include powder, polycrystal and single crystal, of which single crystal is the best material for making high-power electron tube, magnetron, electron beam, ion beam and accelerator cathode. Because of its superior electron emission strength, strong radiation resistance, high temperature chemical stability and other properties, lanthanum hexaboride has been successfully used in radar, aerospace, electronic industry, instrumentation, medical equipment, home appliances, metallurgy and environmental protection and other military and high-tech fields.

Product Detail

product detail

Name: Lanthanum boride, Lanthanum hexaboride Molecular formula: LaB6

CAS: 12008-21-8 Molecular weight: 203.77

Description: Lanthanum hexaborate is a dark purple powder, which is difficult to dissolve in water and hydrochloric acid. In terms of chemical composition, lanthanum borate belongs to inorganic non-metallic materials, and in terms of material properties, it belongs to non oxygen metal refractory compounds. At room temperature, lanthanum hexaborate products have three forms: powder, polycrystal and monocrystal. At present, the preparation of lanthanum hexaborate is generally by boron carbide thermal reduction method, and the reaction formula is La2O3 + 3B4C--2LaB6 + 3CO; because of the introduction of boron carbide as the reaction raw material, the carbon content of the product is difficult to control, and because of the high hardness and large particle size of boron carbide, it is easy to produce the phenomenon of uneven mixture, which makes the chemical composition of the product deviate.
