摘要：

Thermal expansion of MgB2 at normal state is measured experimentally in the temperature range 300-400 K. Lattice and electronic contribution to the thermal exprasion is determined from the Gruneisen relation using electronic and lattice specific heat. This is compared with the low temperature measurements for predicting superconducting transtion.
