摘要：

Microwave sintering of spinel‐type oxides, and more particularly of the ferrite LiFe5O8, was performed in a resonant cavity without use of any absorbent support. The behavior of these materials in a microwave field is similar to those observed for perovskites. However, the quality factor of the cavity is largely dependent on the presence of the ferrite, and modification of the coupling of the cavity is necessary to reach high temperatures. Thus, the difficulty in sintering such material is due more to a drastic decrease of the Q factor than to a cut‐off temperature, as generally believed. Copyright © 1990, Wiley Blackwell.
