Abstract
Improved hot-pressed vitrified bodies are described, which comprise an abrasive material, a vitreous bond; and at least one extender agent. The extender agent may be formed of hollow ceramic bodies such as glass or mullite spheres, alone or in combination with a non-reactive material such as graphite. An improved method for preparing vitrified abrasive wheels is also described.
