研究采用氢 (氘 )化锂粉末松装填充微靶柱腔 ,在氩气保护气氛中以 10℃ /h速度升温至 43 0℃并保温 ,烧结 3 0min ,制备直径 0 6～ 1 0mm、长 1～ 2mm的氢 (氘 )化锂微靶。不添加造孔剂的氢化锂和氘化锂微靶密度分别可达 (0 2 83± 0 0 0 9)g/cm3 和 (0 3 69± 0 0 0 9)g/cm3 。以氘化锂与造孔剂C型环二体混合粉末松装柱腔烧结制备的微靶试样密度达到 (0 3 0 1± 0 0 10 ) g/cm3 。该造孔剂对氘化锂粉末烧结材料的物理品位、氘丰度、6Li丰度无明显影响。严格的氩气保护气氛是防止氢 (氘 )化锂微靶物理品位降低的有效手段
In the study, lithium (deutero) lithium powder was loosely packed into the micro-target column chamber, heated to 43 0 ° C in an argon atmosphere at a rate of 10 ° C / h, incubated for 30 min, and prepared in a diameter of 6 ~ 10 mm 1 ~ 2mm lithium (deuterium) lithium micro-target. The micro-densities of lithium hydride and deuteride did not increase to (0 2383 ± 0 0 0 9) g / cm3 and (0 3 69 ± 0 0 0 9) g / cm3, respectively. The density of micro-target prepared by loosely sintering the deuteride-lithium and pore-forming agent C-ring two-body mixed powder was up to (0 3 0 1 ± 0 0 10) g / cm3. The pore-forming agent has no significant effect on the physical grade of deuterated lithium powder sintered material, deuterium abundance and 6Li abundance. Strict argon atmosphere is to prevent hydrogen (deuterium) lithium micro-target to reduce the physical means of effective means
