Abstract

Since there is much confusion about the temperature correction to the ruby high-pressure scale, we have measured the temperature dependence of the ruby R1 and R2 lines for several ruby samples in the range 150-400 K. The results show a variation of 0.3 Å, corresponding to a pressure of 1 kbar. The results do not depend on chromium concentration. We find that the error in pressure can be reduced to about 0.4 kbar by measuring the temperature dependence of both the R1 and R2 lines of the ruby sample that are used in the high-pressure experiment.
