Experimental investigation of Cr3C2-C peritectic fixed point

High-temperature fixed points of metal-carbide carbon peritectics have transition temperatures close to some of the metal (carbide)-carbon eutectics, and act similar to them in the sense that they can be used at high temperature without being contaminated by the graphite crucibles. The performance seems similar, or maybe even better, in terms of repeatability and plateau shape. In this paper, we focus on the Cr₃C₂-C peritectic point. We encountered difficulty in filling an ingot without voids due to low surface energy of the molten metal. To overcome this, we devised a filling technique taking advantage of the capillary effect. We compared plateau shapes of cells made by different filling methods.
