A method for large-scale production of beryllium oxide ceramic balls by roll forming process |
| abstract |
The invention discloses a method for large-scale production of beryllium oxide ceramic balls by using a rolling forming process. The method includes the following steps: (1) weighing high-purity nanometer beryllium oxide ceramic powder and deionized water, and mixing by ball milling to obtain a beryllium oxide ceramic slurry with a solid content of 55%-66%; (2) beryllium oxide beryllium oxide The ceramic slurry is spray-dried to obtain beryllium oxide ceramic particles with an average particle size of 0.1-0.15 mm; (3) the seeds of the beryllium oxide ceramic particles are slowly added to the pelletizer. Sprinkle nanometer beryllium oxide powder, spray deionized water in a spray mode, continue to roll and shape, until the average diameter of beryllium oxide ceramic ball body is 1.2-3.3mm; (4) place at room temperature and dry to moisture content is 2%-3%; (5) sintering the green body in a high temperature vacuum; the sintering temperature is 1650-1750°C, and the holding time is 3-5h. |
