摘要
Thermal decomposition of original matter such as aluminium hydroxide on exposure to high-intensive radio-frequency electric field is show to be very vigorous to form aluminium oxide of desired physico-chemical properties. An explanation is offered to the mechanism of the hydroxide thermal decomposition. Temperature gradients within a granule are calculated. It is demonstrated that ionization processes in the original material pores result in an added powerful heat source which prevents against their clogging. This method can serve as a basis for high-intensive synthesis of catalysts and carriers with developed surfaces.
