| Popis: | Six samples of beryllium oxide were prepared by calcination in air of hydroxide, sulphate and oxalate to give powders of varied purity. The lattice parameters were calculated from X-ray patterns obtained with a precision camera and found to be equal within the errors of measurement. The parameters of one sample were determined more accurately using a least squares method and a Mercury computer to give the following values at 21dg C: a = 2.6979 ± 0.0001 A, c = 4.3772 ± 0.0002 A. The corresponding density is 3.0100 ± 0.0003 g/cm3. |
