Abstract:
A process for fabricating an article, comprising the steps of:providing a first elongated refractory dielectric body have at least one end face and a second elongated refractory dielectric body having at least one end face;orienting the first and second bodies such that end faces of the first body and the second body are opposite each other wherein the opposing end faces are substantially perpendicular to the longitudinal axis of the first and second bodies, and wherein at least one of the opposing end faces comprises a conical shape;heating the opposing end faces of the first and second bodies with an isothermal plasma torch, such that the plasma is formed between the end faces and the viscosity of the end faces is lowered; andmoving at least one of the bodies such that the heated opposing end faces move together until the end faces are joined.
