Dense bodies of hot-pressed MgO are characterized for impurity or additive LiF or NaF contents and changes with subsequent annealing. As-9hot-pressed bodies from a variety of raw materials and pressing techniques are shown by ir, mass spectrometry, and weight-loss measurements to contain variable amounts of hydroxides, carbonates, and possibly bicarbonates averaging several hundred parts per million in total content. The gases released in the decomposition of these impurities can cause clouding and bloating of bodies on annealing subsequent to hot-pressing, depending on concentration, specimen size and integrity, and heating rates.
