Abstract
Example embodiments relate to a method of measurement, an apparatus for measurement, and an ingot growing system that measure properties relating an induction heating characteristic of a graphite article. The method of measurement comprises an arranging step of arranging a graphite article to the coil comprising a winded conducting wire; and a measuring step of applying power for measurement to the coil through means of measurement connected electronically to the coil, and measuring electromagnetic properties induced in the coil. The method of measurement and the like measure electromagnetic properties of graphite articles like an ingot growing container, and an insulating material, and provide data required for selecting so that further enhanced reproducibility for growth of an ingot can be secured.
