Abstract
Thermal expansion of forsterite, Mg2SiO4, is measured up to 1,600 K by the dilatometric method. The present results of volume thermal expansion Yv is 3.20 percent from 300 to 1,200 K and expansion coefficient αv is 40.5 × 10-6 K-1 at 1,200 K. They are close to those of a natural olivine (Suzuki, 1976), but are 4.4 and 11 percent smaller as compared with those reported in the former paper (Suzuki et al., 1984). The Yv and αv of forsterite are 5.00 percent and 46.7 × 10-6 K-1 respectively, at 1,600 K.
