Abstract
The normal, spectral emittance of two alumina materials, Diamonite and GENDD alumina, was measured over the spectral range from 1 to 8 micrometer and the temperature range from 500 to 1300°C. Both materials consist of 94% alumina by weight, with the remaining 6% comprised of a silica based binder. The binder also contains trace amounts of metal oxides, which vary for the two materials. Emittance data were collected for both materials in the as-received condition and after crystallization of the binder. The emittance results displayed slight spectral variation between the two materials over the range from 1 to 4 micrometer, and for each material there were no noticeable changes in the emittance following crystallization of the binder.
