What Are Canfield Crucible Sets (CCS)

Canfield Crucible Sets (CCS) are two cylindrical crucibles separated by a frit-disc that allows for separation of liquid from solid phase. The frit-disc has a milled shoulder on each side to make what can be a step-taper that allows for simple and effective co-axial alignment of the three-part assembly. The CCS is often used as the containment vessel for solution growth of single crystals. The CCS can be sealed into a morphous silica tubes or even tantalum tubes. The precise dimensions of the set can be chosen to fit within specific tubing. Separation of crystalline phase from remaining liquid is often accomplished with the aid of a laboratory centrifuge.

Abstract: Solution growth of single crystals from high temperature solutions often involves the separation of residual solution from the grown crystals. For many growths of intermetallic compounds, this separation has historically been achieved with the use of plugs of silica wool. Whereas this is generally efficient in a mechanical sense, it leads to a significant contamination of the decanted liquid with silica fibers. In this paper, we present a simple design for frit-disc alumina crucible sets that has made their use in the growth single crystals from high temperature solutions both simple and affordable. An alumina frit-disc allows for the clean separation of the residual liquid from the solid phase. This allows for the reuse of the decanted liquid, either for further growth of the same phase, or for subsequent growth of other, related phases. In this paper, we provide examples of the growth of isotopically substituted TbCd and icosahedral i-RCd quasicrystals, as well as the separation of (i) the closely related and phases and (ii) and ...
