What are the Factors for Selecting a Crucible?

There are several factors one needs to consider when selecting a crucible, this can seem a daunting task because there are several things to consider. These factors can range from needed volume, the shape, and the chemical reactions between the crucible and the chemicals you put in it no name just a couple. Here is a list of some of the most important factors to consider when selecting a crucible. 

  • What temperature will the crucible need to withstand?
  • What material crucible will be selected?
  • Is the material in the crucible going to react with the crucible?
  • Is the ramp rate being used going to thermally shock the crucible?
  • Is there a thermal gradient across the crucible, if so how will that affect the crucible?
  • What volume crucible will I need?
  • Will the geometry of the crucible be important?
  • Will the crucible fit in the furnace?
  • Is the crucible going to be used more than once?

This might seem a daunting list of questions to answer, but if you have ever chosen the wrong crucible for the job and ended up rebuilding your furnace you know the importance of answering these questions.
