  • Patent number: 4977024
    Abstract: A magnesia granule having a surface covered with a continuous and uniform coating of silica or forsterite, and suitable for use as a filler. The magnesia granule is prepared by a process comprising granulating a magnesia powder into a spherical shape, heat treating the granular particles at a temperature in a range of from 1400.degree. C. to 1700.degree. C. for not more than 1 hour, and then subjecting the particles to gas-solid phase mixing with a heated vapor of an organic silicate compound in a fluidized bed reactor to cover the surface of the granular magnesia particles with a continuous and uniform coating of silica, or a process comprising granulating a magnesia powder of particles coated with a silica layer into a spherical shape, and then heat treating the granular particles at a temperature in a range of from 1400.degree. C. to 1700.degree. C. for not more than 1 hour to cover the surface of the granular particles with a continuous and uniform coating or forsterite.
