FABRICATION METHOD OF LITHIUM CERAMICS PEBBLES USING SLURRY DROPLET WETTING METHOD

摘要

PURPOSE: A production method of a lithium ceramics pebble is provided to easily control a microstructure of the lithium ceramics pebble by controlling the sintering temperature and using a slurry droplet wet process. CONSTITUTION: A production method of a lithium ceramics pebble comprises the following steps: mixing lithium ceramics powder with a binder and deionized water mixture solution to obtain lithium ceramics slurry; dripping the lithium ceramics slurry in a hydroperoxide solution to obtain droplets; and drying and sintering the droplets. 7-20 wt% of binder is mixed in the binder and deionized water mixture solution. The concentration of the hydroperoxide solution is 5-40 wt%. The diameter of the droplets is 0.5-4.0 mm. The drying process is conducted at room temperature, and the sintering process is conducted at 600-1,300°C.
