METHOD OF MEASURING LINEAR EXPANSION THERMAL COEFFICIENT Russian patent published in 2006 - IPC G01N25/00

Abstract RU 2271534 C1

FIELD: measurement technology.

SUBSTANCE: method can be used for measuring linear expansion coefficient of hard bodies within wide temperature range. Lattice period for whicker crystal is determined preliminary by X-ray method. Change in lattice period is calculated depending on temperature and coefficient to be found is determined while taking mentioned dependence into account.

EFFECT: reduced labor input.
