Lining type container used for precious metal crucible and preparation method thereof
The invention relates to a lining type container used for a precious metal crucible and a preparation method thereof. According to the technical scheme, boronic acid powder and lithium carbonate powder are evenly mixed according to the mole ratio of 4:1 to obtain mixed powder; then, pure water is sprayed to the mixed powder, the sprayed pure water accounts for 0.1-2 wt% of the mixed powder, stirring is carried out till mixing is uniform, and a mixed material is obtained; the obtained material stands still under the condition of 10-40 DEG C till the mixed material accounts for 82-88 wt% of the mixed material before still standing, and a lithium tetraborate half-dry material is obtained; then the lithium tetraborate half-dry material is formed to obtain a crucible lining container blank; finally, the crucible lining container blank is placed in an oven, dried for 2-3 hours under the condition of 105 DEG C and sintered for 1-3 hours under the condition of 700-850 DEG C; cooling is carried out, and the lining type container used for the precious metal crucible is obtained. The container has the advantages that energy consumption is low, manufacturing is easy, the production period is short, equipment utilization efficiency is high, cost is saved, and the precious metal crucible is long in service life.
