Preparing and Characterization of Hollow Ceramic Microspheres

The hollow microsphere is a kind of new materials .Its comprehensive performance is excellent and has a bright future. This article introduces a high-temperature synthetic technology on the basis of SHS to prepare new hollow ceramic microspheres. Reaction mechanism of hollow ceramic microspheres was studied. Results show that sphere, similar sphere and irregular powders constitute the spraying products. Sphere and similar sphere powders are hollow structure. Besides it alsorecommend the self-made equips of collection that adopts three kinds of collections methods of static electricity, water and filter net. The total rate of collection raised above 80%. The effect is good. The hollow microsphere were analyzed through SEM and XRD, the hollow microsphere is regular spheroid or type spheroid. The size of the hollow microsphere is similar. Its diameter is or so for 20 gm. The equipments that experiment needs is simple, vivid craft and strong adaptability and respond that raw material and manufacturing circulate cost cheap.
