METHOD AND APPARATUS FOR HEAT TREATMENT OF GLASS MATERIALS AND NATURAL MATERIALS SPECIFICALLY OF VOLCANIC ORIGIN |
摘要 |
A method of heat treatment of glass materials and natural materials specifically of volcanic origin according to which the treated material is exposed to microwave radiation at a frequency range from 1 MHz to 10 GHz and temperature range from the ambient temperature to 1800° C. in a batch or continuous process. The glass or natural material subjected to a melting and/or refining process contains an inert additive elected from the group comprising carbides, nitrides or borides in an amount from 1 to 100 g preferably 5 to 50 g per 1 kg of the glass or natural material. The apparatus consists substantially of a microwave furnace comprising an outer shell ( 8.2 ) provided with a cover ( 10 ) and an inner shell ( 8.1 ) and at least one micro wave generator ( 1.1, 1.2, 1.3, 1.4 ) with double emission and total power from 0.1 to 1 kW per 1 kg of the treated material. |
