Method for carrying out direct ceramization treatment on high-level waste by utilizing microwaves
The invention discloses a method for carrying out direct ceramization treatment on high-level waste by utilizing microwaves. The method comprises the following steps: 1) grinding and drying the high-level waste to obtain dry powder; 2) carrying out tabletting operation on the dry powder to obtain blocky wastes; and (3) the blocky waste is placed in a microwave sintering furnace to be sintered, the sintering temperature is 1100-1400 DEG C, heat preservation is conducted for 2-4 h at the sintering temperature, and the high-level waste ceramic solidified body is obtained after cooling. The invention provides a microwave sintering technology which is energy-saving, high in temperature rising speed and capable of improving the performance and reducing the sintering temperature, and the obtained high-level waste ceramic solidified body has the advantages of high hardness, good chemical stability and the like, and can effectively inhibit the high-level waste from polluting a biosphere. The method disclosed by the invention has relatively high use value and development potential.
本申请公开了一种利用微波直接陶瓷化处理高放废物的方法,包括以下步骤:1)将高放废物进行研磨,干燥后得到干燥粉末;2)对干燥粉末进行压片操作,得到块状废物;3)将块状废物置于微波烧结炉中进行烧结,烧结温度为1100℃~1400℃,烧结温度下保温2h~4h,冷却后得到高放废物陶瓷固化体。本发明提供了一种节能、升温速度快、改善性能、降低烧结温度的微波烧结技术,所得的高放废物陶瓷固化体具有硬度高、化学稳定性好等优点,能够有效抑制高放废物污染生物圈。本发明的方法具有较高的使用价值和发展潜力。
