| Influence of minor additions of MgO, Ti01 and Fe10 1 on BeO
powders prepared by calcination of tbe hydroxide bas been studied.
Minor additions have no significant influence on the decomposition
characteristics of beryllium hydroxide. Depending on the temperature
of calcination, tbe minor additions have varying degree of inHuence on
surface area, crystallite size, particle size and particle morphology.
Reduction in surface area and increase in crystallite size with increase
in calcination temperature were dependent on the type of tbe additive
present. The crystallite size and particle size were of the same order
of magnitude at lower calcination temperature. With increase in
calcination temperature. the particle growth was much more than the
crystallite growth. |
