When charging the quartz crucible, the wrong way will not only cause the loss of the crucible, but also lead to poor charging effect and affect the later use effect.

1, when filling the block, below the liquid level line, should be packed as dense as possible, in the lower part of the block and the wall should be taken surface contact. The block material above the liquid level line should be better at the point contact surface, so as to avoid deformation caused by the quartz crucible pulling inward and bending due to hanging edge in the solvent.

2, in the filling of small fragments, should try to put the small material into the lower part of the quartz crucible, do not pour all the fragments above the crucible, in the loading can leave part of the block on the top of the small material. In this way, when the lower material is dissolved, the upper block will bring the debris down by its own gravity.

Therefore, when we load the quartz crucible, we must pay attention to the above two points, and load in accordance with the correct loading method. At the same time, before loading the crucible, it is necessary to do a detailed check on the crucible to ensure that the crucible has no abnormal problems before loading. This can ensure that the crucible can be used normally, so as to avoid problems during use.
