Abstract
A method of manufacturing an insulator for a spark plug comprises the steps of combining at least two raw materials to form a powdered insulator formulation, spray drying the powdered insulator formulation, and pressing the powdered insulator formulation to create an insulator blank. The method further includes the steps of bisque firing the insulator blank, grinding the bisque fired insulator blank to form the insulator, and sintering the insulator.
