Method for producing beryllium oxide ceramic balls in large scale by adopting rolling forming process
The invention discloses a method for producing beryllium oxide ceramic balls on a large scale by adopting a rolling forming process. The method comprises the following steps: (1) weighing high-purity nanometer beryllium oxide ceramic powder and deionized water, and carrying out ball milling and mixing to obtain beryllium oxide ceramic slurry with the solid content of 55-66%; (2) carrying out spray drying on the beryllium oxide ceramic slurry to obtain beryllium oxide ceramic particles with the average particle size of 0.1-0.15 mm; (3) slowly adding the beryllium oxide ceramic particle seeds into a pelletizer, spraying the nano beryllium oxide powder on the seeds while spraying deionized water in a spraying manner in the rotating process of the pelletizer, and continuously rolling and forming until a beryllium oxide ceramic ball blank with the average diameter of 1.2-3.3 mm is obtained; (4) drying at room temperature until the water content is 2-3%; (5) performing high-temperature vacuum sintering on the green body; the sintering temperature is 1650-1750 DEG C, and the heat preservation time is 3-5 hours.
本发明公开了一种采用滚制成型工艺规模化生产氧化铍陶瓷球的方法。该方法包括下述步骤：(1)称量高纯纳米氧化铍陶瓷粉体和去离子水，经过球磨混合后得到固含量为55％‑66％的氧化铍陶瓷料浆；(2)氧化铍陶瓷料浆进行喷雾干燥，得到平均粒径为0.1‑0.15mm的氧化铍陶瓷颗粒；(3)氧化铍陶瓷颗粒种子缓慢加入造球机中，在造球机转动的过程中，一边在种子上洒纳米氧化铍粉末，一边以喷雾的方式喷入去离子水，持续滚制成型，直至得到平均直径为1.2‑3.3mm氧化铍陶瓷球坯体；(4)置于室温下干燥至含水率为2％‑3％；(5)将坯体高温真空烧结；所述烧结温度为1650‑1750℃，保温时间3‑5h，即得。
