โœฆ Synopsis

The specific heat of glassy carbon was investigated in the temperature range of 0*44-4*5"K. The specific heat follows a relation C = aT3+ yT, with y going through a ma~mum and a! increasing with increase in heattreatment temperature. On the average the cubic specific heat term is about the same as for soft carbons heattreated to IOOO-1200ยฐC. In the lowest temperature range evidence of the presence of a specific heat peak below 0.44"K is obtained. The high temperature tail of this peak at first increases and subsequently disappears with increasing heat-treatment.
