- a microwave apparatus typically comprises an oven in which the reacting material is put and then irradiated with radio waves at high frequency.
- Microwaves are generated by a Magnetron that causes an electronic beam to oscillate at a very high frequency, thus creating microwaves, or more recently they are generated by solid state oscillating devices .
- These apparatus have relevant advantages with respect to traditional heat source . In fact, they are capable of providing an exceptionally quick heating of the reacting material and of quickly achieving higher temperatures than other conventionally used systems .
- reactors used for this type of technology have to be made of suitable materials, i . e . materials transparent to microwaves .
- the used microwave reactors are normally closed in containers with metal walls that are scarcely manageable and are accessible in a difficult way. Furthermore, it is not possible to use microwaves in case of reactions that take place at high pressures, since metal reactors are required with high thicknesses , and for these reactions they cannot be crossed by microwaves .
- Other drawbacks are the high cost and the high energy consumption required by the microwave technology that strongly limits its diffusion on a large scale .
- microwave heating apparatus for chemical-physical processes, according to the present invention, said apparatus comprising: a microwave source,
