Description
Spherical Alumina particles obtained by oxy-propane gas flame spraying were investigated by means of scanning electron microscope and X-ray powder diffraction. The ratio of spherical and nomspherical particle was influenced by powder concentration in the flame, carrier gas and activity of the raw alumina powders.<br>The surface conditions of alumina spheres were divided into two categories; dendritic and granular form.<br>The crystal form of sphere was composed of α-and δ-alumina. Formation of δ-alumina progressively decreased with the sphere diameter. Allotropic transformation of δ-to α-alumina was completed at 1300°C for 3h.
