Hydrolyzed ceramic ball inner core, ceramic ball and preparation method of ceramic ball
The invention discloses a hydrolyzable ceramic ball inner core, which is prepared from the following components in percentage by mass: 5 to 20 percent of Al2O3, 0.5 to 3 percent of SiO2, 1 to 10 percent of ZrO2, 5 to 40 percent of MgO, 15 to 50 percent of CaO, 10 to 50 percent of BaO, 0.5 to 40 percent of SrO, 0.1 to 1 percent of Y2O3 and 0.2 to 3 percent of CeO2. The invention also discloses a ceramic ball containing the hydrolyzable ceramic ball core. The invention also discloses a preparation method of the ceramic ball containing the hydrolyzable ceramic ball core. According to the invention, a certain amount of glass phase and ceramic skeleton are formed during sintering of the inner core, and the inner core has certain ceramic strength, so that the overall strength of the target ceramic ball can be ensured not to be greatly influenced by the inner core; meanwhile, surplus alkaline-earth metal oxides generated in the sintering process can be stored, the ceramic ball is gradually abraded and becomes small in the using process, and when the ceramic ball reaches the inner core, the alkaline-earth metal oxides on the inner core can generate hydrolysis reaction and gradually swell when meeting water, so that the inner core can be quickly consumed.
本发明公开了一种会水解的陶瓷球内核，包括以下质量百分数的组分：Al2O3:5~20%、SiO2:0.5~3%、ZrO2:1~10%、MgO:5~40%、CaO:15~50%、BaO:10~50%、SrO:0.5~40%、Y2O3:0.1~1%、CeO2:0.2~3%。本发明还公开了一种含会水解的陶瓷球内核的陶瓷球。本发明还公开了一种含会水解的陶瓷球内核的陶瓷球制备方法。本发明中内核烧结时形成一定量的玻璃相和陶瓷骨架，具有一定的陶瓷强度，可以确保目标陶瓷球整体的强度不受内核太大的影响；同时烧结过程产生的富余碱土金属氧化物会保存下来，陶瓷球在使用过程中逐渐磨损变小，达到内核时，内核上的碱土金属氧化物遇水即会产生水解反应，逐渐膨解，使得内核会被迅速消耗。
