See our full range of Tapered Wall crucibles. These crucibles are cylindrical shaped with a tapered wall. As a result they have a smaller diameter at the base, than at the mouth.
The tapered wall crucibles are available in two materials. High purity recrystallized Alumina (99.9%) and Yttria stabilized Zirconia. They offer varying degrees of temperature and thermal shock resistance. 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.
