PROCESS FOR HEATING A FLUID AND AN INJECTION MOLDED MOLDING

摘要

A process for heating a fluid includes providing an injection molded molding made of a ceramic material with a positive temperature coefficient containing less than 10 ppm of metallic impurities, and using the injection molded molding to heat a fluid. For a straight line through the injection molded molding, at least two cross sectional areas perpendicular to the line cannot be superimposed on each other via a translation along the line,
