Purification of LiF Powder by Zone Melting Method
In order to achieve high quality crystals, it is necessary to purify the raw material. In the present experimental study, the zone melting method was used to purify Lithium Flouride powder. A small amount of melt moves slowly from the solid area in order to remove impurities in the frozen solid. In...

| description | In order to achieve high quality crystals, it is necessary to purify the raw material. In the present experimental study, the zone melting method was used to purify Lithium Flouride powder. A small amount of melt moves slowly from the solid area in order to remove impurities in the frozen solid. In this case, the number, size and length of the zone melting affect the final result, and cause the optimal distribution of solutes. At the beginning, the regional purification system was equipped. The mechanism of work was moving furnace on a graphic crucible with full of LiF powder by 20 mm/h-1. This procedure was followed in a vacuum for 7, 9 and 14 times. At last the amounts of impurities such as Fe, Ba were measured by ICP (Inductively Coupled Plasma) analysis before and after purification. |
