High-temperature oxidation of sintered lanthanum hexaboride

Conclusions The intense interaction between sintered LaB₆ with atmospheric oxygen starts, at temperatures close to 700°C, The mechanism of the process and composition of the interaction products change depending on temperature. Oxidation resistance of LaB₆ up to 1200°C is satisfactory. At higher temperatures, catastrophic oxidation of the material caused by active evaporation of boron oxide takes place.Translated from Poroshkovaya Metallurgiya, No. 11(299), pp. 56–59, November, 1987.     

Emissive electric-spark coatings based on lanthanum hexaboride

Conclusions The electric-spark alloying of metals and steels with lanthanum hexaboride and its alloys results in the formation of heterophase coatings whose principal phase constituent is a lower boride of the basis metal. The coatings contain also a small amount of a LaB₆-base phase, whose presence ensures that their level of emission is close to that of LaB₆ itself. By varying the composition of the alloy and using different basis materials, it is possible to exercise control over the efficiency of deposition of coatings and their thermionic emission properties.Translated from Poroshkovaya Metallurgiya, No. 2(254), pp. 50–53, February, 1984.
