The method includes the steps of applying microwave radiation to a sample in a sealed vessel while measuring the temperature of the sample and measuring the pressure generated inside the vessel and until the measured pressure reaches a designated set point, opening the vessel to release gases until the pressure inside the vessel reaches a lower designated set point, closing the vessel, and repeating the steps of opening the vessel at designated pressure set points and closing the vessel at designated pressure set points to the sample until the sample reaction reaches a designated high temperature. The designated set points can controllably differ from one another as the reaction proceeds. Microwave energy can be applied continuously or intermittently during the opening and closing steps. The apparatus includes a microwave cavity, a microwave transparent pressure resistant reaction vessel in the cavity, a cap on the reaction vessel, a pressure sensor for measuring pressure in the vessel, a temperature sensor, and means for opening and closing the cap at predetermined pressure set points measured by the pressure sensor to release pressure from the vessel.

Abstract: An industrial microwave ultrasonic reactor has an inner wall liner. A microwave generation device is formed by microwave units distributed on an outer sidewall, or by a microwave pipe disposed outside the reactor and microwave units distributed on the microwave pipe. One end of the microwave pipe communicates with the bottom of the reactor via a connection pipe I, and the other end communicates with the top via a return pipe. A shield is disposed outside the microwave generation device to separate the microwave units from the outside, and a heat removal device is disposed outside the shield. An ultrasonic wave generation device is formed by 10 to 30 sets of ultrasonic pulse units disposed at intervals along the outer sidewall. Each set has 10 to 50 members distributed along the circumferential direction of the reactor. A stirring shaft is fixed below a stirring motor and extends into the reactor.

Abstract: A method and apparatus for rapidly preprocessing and analyzing chemical substances, which places a vaporization bottle containing a sample inside a microwave device and uses a magneton driving device to drive the magneton inside the vaporization bottle to rotate as to stir the sample liquid even. In the meantime, the radiation of the electromagnetic wave of the microwave device is used to activate the molecules of the sample liquid to move, causing the tested chemical substance in the sample liquid to be vaporized in a very short time. Therefore, the tested chemical substance can be absorbed or adsorbed by the absorbing medium to greatly reduce the sample preprocessing time and increase the quantity of the tested chemical substance sample. The detection limits of a tested chemical substance are therefore lowered without using organic solvents.

Abstract: A method for producing silicon using microwave and a microwave reduction furnace for use therewith are disclosed, with which it is possible to quickly reduce silica to quickly produce silicon. A material of a mixture of a silica powder and a graphite powder of a mixture of a silica powder, a silicon carbide powder and a graphite powder is set in a refractory chamber. Then, the material set in the chamber is irradiated with microwave. The graphite powder absorbs a microwave energy to increase the temperature, after which silica and graphite react with each other to further increase the temperature while producing silicon carbide, and the heated silica and silicon carbide react with each other. SiO produced through this reaction and silicon carbide are allowed to react with each other, thereby producing high-purity silicon.
