Abstract
Potassium bromide single crystals have been prepared with 10.6-μm bulk absorption coefficients smaller than the intrinsic value for potassium chloride. Of several halogen-producing vapors studied, that of carbon tetrachloride is most effective in decreasing infrared absorption. Water-grinding, followed by polishing with HBr solutions, produces non-absorbing and etch-pit-free surfaces on planes remote from (100). Hydroxyl lines are absent from infrared absorption spectra of all crystals. Vacuum-ultraviolet absorption at 215 nm shows presence of between 0.01 and 4.0 OH- ions per million anions. Incomplete removal of metaborate (BO-2) by iodine monobromide or by hexabromobenzene is evident in infrared absorption spectra.
