Abstract

1398143 Lanthanium strontium chromite SQUARE D CO 29 June 1973 [18 July 1972] 33656/72 Heading C1A [Also in Division C7] Lanthanum strontium chromite of the formula which x has a value between -0 and 1 is produced by spray decomposition of a mixture of lanthanum, strontium and chromium nitrates to produce the mixed oxide powder which can then be sintered, milled and washed for use as an electrical contact material with silver. Exemplified materials have a value for x of 0À7.
