Preparation method of silicon carbide hollow spheres
The invention discloses a preparation method of silicon carbide hollow spheres, and belongs to the technical field of high-strength non-metallic materials. According to the technical scheme, the method comprises the following steps: (1) repeatedly spraying liquid by using non-toxic and volatile organic matters through ball making equipment, adding powder, and carrying out rolling forming to prepare microbeads; (2) screening microspheres as seeds; (3) putting the seeds with the weight being 5-10% of the target weight into ball making equipment; (4) repeatedly spraying liquid and silicon carbide powder on the surfaces of the seeds, rolling and forming to prepare shell silicon carbide microspheres; (5) screening shell silicon carbide microspheres; and (6) putting the screened shell-layer silicon carbide microspheres into a kiln, drying, roasting, calcining and cooling to obtain the silicon carbide hollow spheres. The method is simple, and the prepared silicon carbide hollow spheres have the characteristics of light bulk specific gravity, high compressive strength, high temperature resistance, long service life and the like, so that the protection capability of the bulletproof armor on military machinery and military facilities is improved.
本发明公开了一种碳化硅空心球的制备方法，属于高强度非金属材料技术领域。其技术方案为：包括以下步骤（1）用无毒可挥发的有机物经制球设备反复喷液体加粉体滚动成型制作微珠；（2）筛选微珠作为种子；（3）将目标重量5‑10%的种子放入制球设备中；（4）在种子表面反复喷液体加碳化硅粉，滚动成型，制作成壳层碳化硅微球；（5）筛选壳层碳化硅微球；（6）将筛选之后的壳层碳化硅微球放入窑炉经烘干、焙烧、煅烧、降温制得碳化硅空心球。本发明方法简单，制备出的碳化硅空心球堆积比重轻、抗压强度高、耐高温、使用寿命长等特点提高防弹装甲对军工机械和军事设施的防护能力。
