See our full range of Point Bottom crucibles, primarily used as crystal growing alumina crucibles. These point bottom crucibles have a test tube shape, with the closed end ending in a point.
The point bottom crucibles are available in two materials. High purity recrystallized Alumina (99.8%) and Yttria Stabilised Zirconia. They offer varying degrees of temperature and thermal shock resistance and will perform differently as a result. There is a price difference between the two materials and you therefore may need to consider which is most suitable for your use case.
