Abstract
A heating element for heating crucibles, including a cylindrical hollow body which is divided by slits into meandrous segments. The corners between adjacent lateral surfaces of the meanders are rounded. Sectional transition areas are located in the vicinity of the upper and lower edges of the meandrous segments. Each sectional area has an outer rounded edge with a radius of curvature equal to the individual length of each meandrous section.
