A rapid and very simple technique using induction heating is reported for obtaining the spectral, or total, emissivity of a ceramic material up to its melting point. The measurement system employs a PbS detector, in conjunction with a sensitive galvanometer. Spectral emissivity data are shown for several alumina bodies and for three rare‐earth oxides, erbium, samarium, and gadolinium, up to 1700°C.
