A vertical float zoner combined with thermal imaging is uniquely suited to investigation of high‐temperature noncontaminating melts by X‐ray diffraction. Radiation from a halogen lamp is focused on the sintered‐powder rods by means of the gold‐plated internal surface of an ellipsoidal shell. This image furnace can easily be mounted on a conventional horizontal type of powder diffractometer, provides atmosphere control, and permits rapid heating and cooling. A temperature of 1700°C can readily be reached. The presence of a gap for the passage of X‐rays solves the problem of X‐ray absorption by window materials, and sufficient lateral length of the gap allows X‐ray measurement over a wide diffraction range.
