SIGNIFICANT ENHANCE OF THE INDIRECT MICROWAVE HEATING YIELD IN THE FOAMING PROCESS OF GLASS WASTE
Keywords:
yttrium oxide, foaming, microwave, glass foam, glass waste
Abstract
The paper contains testing results of an intensification method of the remarkable microwave absorbing capacity of a silicon carbide crucible coated with a yttrium oxide layer, applied in the sintering/ foaming process of the glass waste. Using the same type of microwave oven and same composition of raw material and foaming agent as in previous tests, the functional parameters of the process were significantly enhanced without altering the characteristics of products made by known conventional and nonconventional techniques.
