Abstract
ONLY two values of the thermal conductivity of barium strontium oxide have been published: 0.00034 cal. deg.−1 cm.−1 sec.−1 obtained by Clausing and Ludwig1, and 0.000123–0.0013 cal. deg.−1 cm.−1 sec.−1 by Patai and Tomaschek2. Hamaker3 pointed out, however, that the methods employed by these workers were open to objections, since they depended on optical pyrometric measurements made on coated cathodes, and no allowance was made for the semitransparency of the coating.
