  1. Способ производства порошка a -глинозема включает стадию прокаливания переходного глинозема или предшественника переходного глинозема, способного превращаться в переходный глинозем при нагревании в газовой атмосфере, содержащей галогенводород, смесь галогена и водяного пара или галогена, в присутствии затравочных кристаллов и/или формо-регулирующего агента. Порошок глинозема чрезвычайно пригоден как сырьевой материал для производства абразивов, наполнителей, спеченных материалов, заполнителей пустот, которые состоят из частиц a -глинозема с узким распределением преимущественного размера, в основном октаэдрической или икосаэдрической формой и особенной структурой.
