摘要
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 )
Low density 6Li(H,D) micro targets are prepared by loose sintering 6LiH or 6LiD powder in a tiny gold cylinder and soaking for 30 min up to 430 ℃ at the rate of 10 ℃/h in argon. The dimension of the micro targets is as tiny as 0.6～1.0 mm for diameter and 1～ 2 mm for length. Densities of 6LiH and 6LiD without parylene C is (0.283±0.009) g/cm 3 and (0.369±0.009) g/cm 3, respectively while 6LiD targets with parylene C is only (0.301± 0.010 ) g/cm 3. The parylene C has no effect on purity, deuterium abundance and 6Li abundance of the sintered micro targets. It's effective to keep 6Li(H,D)purity by strict control of argon atmosphere.
