Abstract
Specific heat measurements have been made on niobium (from 1471 to 22600K), molybdenum (from 1288 to 2015�K), tantalum (from 1256 to 23000K), and tungsten (from 1267 to 24100K). The experiments were based on a theory first proposed by Corbino in 1911. It is demonstrated that methods based on this theory account for heat losses from the specimen under test to better than 0'5% even at 2400oK. The theory requires a knowledge of the temperature oscillations in thin a.c. heated filaments and this amplitude is here obtained from photoelectric measurements.
