~(153)Gd骨密度计源芯体的烧结工艺为:将加有4%石蜡的~(153)Gd_2O_3粉末于专用模具中压制成形,再于1400℃氢气气氛中烧结成直径3mm、厚度1mm及放射性活度大于3.7×10~(10)Bq的骨密度计源陶瓷芯体。
The sintering process of ~ (153) Gd BMD source core was as follows: a powder of ~ (153) Gd_2O_3 added with 4% paraffin was press-molded in a special mold and sintered in a hydrogen atmosphere at 1400 ° C to a diameter of 3 mm and a thickness of 1 mm And bone mineral density meter source ceramic core with radioactivity greater than 3.7 × 10 ~ (10) Bq.
