Lightweight ceramic ball and preparation method thereof
The invention relates to a lightweight ceramic ball and a preparation method thereof, belongs to the technical field of ceramics, and solves the problems of high mechanical strength, rich pores and high water absorption of the existing ceramic ball. Comprising the following steps: uniformly mixing first ceramic raw material powder, a sintering aid and a binder to obtain first mixed powder, and pelletizing the first mixed powder to prepare inner shell balls; the first ceramic raw material powder is light powder or a porous raw material; uniformly mixing second ceramic raw material powder, a sintering aid and a binder to obtain second mixed powder, scattering the second mixed powder onto the surface of the inner shell ball, and pelletizing to obtain a double-layer ceramic ball; the second ceramic raw material powder is low-melting-point high-strength powder; the third ceramic raw material powder is scattered on the surfaces of the double-layer ceramic balls, pelletizing is conducted, and ceramic balls are obtained; the melting point of the third ceramic raw material powder is higher than that of the second ceramic raw material powder; and drying and sintering the ceramic ball, and then removing the third ceramic raw material powder to obtain the light ceramic ball. According to the invention, the high-strength light ceramic ball with near-zero water absorption can be obtained.
本发明涉及一种轻质陶瓷球及其制备方法，属于陶瓷技术领域，解决了现有陶瓷球机械强度高，孔隙丰富但吸水率较高的问题。包括：将第一陶瓷原料粉、烧结助剂和粘结剂混合均匀得到第一混合粉，将第一混合粉进行团球，制备得到内壳球；第一陶瓷原料粉为轻质粉或多孔原料；将第二陶瓷原料粉、烧结助剂和粘结剂混合均匀得到第二混合粉，将第二混合粉撒到内壳球表面，进行团球，得到双层陶瓷球；第二陶瓷原料粉采用低熔点高强度的粉料；将第三陶瓷原料粉撒到双层陶瓷球表面，进行团球，得到陶瓷球；第三陶瓷原料粉的熔点高于第二陶瓷原料粉的熔点；干燥、烧结陶瓷球后除去第三陶瓷原料粉，得到轻质陶瓷球。本发明能够得到高强度近零吸水率轻质陶瓷球。
