Kanolt] Melting Points of some Refractory Oxides 299 reliable to o.ooi ampere and probably to 0.0005 ampere.… … These materials were melted in the Arsem fmnace in graphitecrucibles, similar to that shown in Fig. 3, but entirely closed atthe top to prevent contamination. Heating orcooling curves were plotted. This method hasalready been described.^ In the present work some crucibles were usedin which the…
