Magnesia powders, prepared by the decomposition of have been examined by measurements of density, surface area, and heat of solution and the particles examined by electron micrographs. Oxide prepared by low-temperature decomposition is active, having a high surface area and a high heat of solution, both of which decrease with increase in temperature of calcination. Powders prepared in vacuo are more ''active'' than those prepared in air, having a greater surface area and greater heat of solution for a given temperature of preparation. The properties of active powders are considered in relation to general sintering phenomena and the sinterability of these powders is illustrated. (auth)
