Abstract
A refractory coating material that can be used to coat a wide variety of surfaces or substrates to provide thermal and mechanical protection. The refractory coating material can withstand exposure to use temperatures of about 1500° C. and greater, yet the fibers contained therein exhibit low biopersistence in physiological fluids such as simulated lung fluid. Also disclosed are methods for making and utilizing the refractory coating material.
