WAYS OF OBTAINING SUPER-STRONG UNBREAKABLE GLASS
Abstract
A N IMPORTANT SHORTCOMING OF GLASS IS IT LOW SILE STRENGTH WITH CONSEQUENT BRITTLENESS AND LOW HEAT RESISTANCE. Co fficients of brittleness (the reciprocal of maximum relative deformation) ar giv for glass and several other materials. The elimination of microdefects may increase t nsile s rength a hundred times OME WAYS TO REMOVE DEFECTS ARE: PICKLING IN HF to remove surface cracks; heating in a vacuum at high temperature to remove gases; cooling under great pre sure to prevent microcracks; and gamma irr di tio during melting and cooling to prevent crystallization. Tensile strength may be increa d by forced polymerization induced by powerful sonic or ultrasonic waves. (Author)
