1、Levitation melting is used instead of graphite crucible heating.
2、Reduction experiments have been conducted in a vertical tube furnace using graphite crucible.
3、Large size CaF_2 crystal has been grown by the Bridgman-Stockbarger method using a graphite crucible.
4、The results show that silver based electric materials ought to be smelted by graphite crucible, the clay crucible is suitable for smelting silver based solder.
5、In accordance with the conventional production process, the loss of lithium is often about 7%, when Al-Li alloy is melted in graphite crucible.
6、The results show that the main components of inclusion are carbon and oxygen. Carbon impurity comes from graphite crucible and heater, while oxygen impurity from the oxides in the raw material…
7、It is found that yttria has a good stability to liquid uranium and its alloys at high temperature, and it is well suitable for coating of graphite crucible for melting uranium and its alloys.
8、The fusion of samples is performed in graphite crucibles using low dilution fusions with mixed flux. The calibration is done by use of synthetic standards.
