Abstract

The invention provides a ceramic microsphere as well as a method and a device for preparing the ceramic microsphere by using a suspension photo-curing method. The method for preparing the ceramic microsphere by the suspension photo-curing method comprises the following steps that ceramic slurry containing a photo-curing agent is dropped in a suspending agent in a non-continuity mode, and liquid drops of the ceramic slurry are gradually sunken in the suspending agent to be converted into spherical liquid drops; the spherical liquid drops are irradiated by ultraviolet rays so as to excite the photo-curing agent in the spherical liquid drops to be solidified, and then a ceramic microsphere green body is formed; the separated ceramic microsphere green body is dried and discharged glue so as toremove organic components, and a ceramic microsphere precursor is obtained; and the ceramic microsphere precursor is sintered at high temperature to obtain the ceramic microsphere. According to the technical scheme of the method and device, the morphology, the size and the internal structure of the prepared ceramic microsphere are more controllable, so that the preparation of the ceramic microsphere is standardized, systematized, automatic and large-scale, and the ceramic microsphere with the micron-scale particle size can be prepared.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to ceramic microspheres, a method and a device for preparing ceramic microspheres by a suspension light curing method. Background technique [0002] Ceramic microspheres refer to inorganic non-metallic sintered bodies with particle sizes ranging from microns to millimeters, in the form of spheres or approximate spheres, and in various forms such as dense and porous microspheres. Monodispersed millimeter-scale ceramic microspheres are widely used in nuclear reactors, composite materials, catalysis, separation and purification, and medicine. Lithium-containing ceramic microspheres can be used as a solid tritium value-added agent, which has the advantages of convenient use and good thermal and mechanical properties. Ceramic microspheres can also be used as reinforcing fillers for plastic, rubber, and nylon products to make the filling even. Ceramic microspheres can also be used as a ...
