Abstract: A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal reacts with the nitrogen to produce the metal nitride, and the molten salt provides a new reaction interface for the metal nitride to react with the hydrogen to synthesize ammonia, so that ammonia is produced continuously. In addition, the molten salt prevents the liquid alloy from contacting with the oxygen and the water vapor, which prevents the liquid alloy from being oxidized, thus prolonging its service life.

Abstract: A reactor 200 according to the present invention includes a heater storage section serving as a space section capable of accommodating a carbon heater for initial heating of silicon core wires. A carbon heater 13 is loaded in a deposition reaction space 20 in the reactor 200 only when necessary for initial heating of silicon core wires 12. After initial heating of the silicon core wires 12 is finished, the carbon heater 13 is unloaded from the deposition reaction space to the heater storage section 30. As a result, the carbon heater 13 is not unduly damaged in the reactor any longer and its deterioration is reduced. In addition, because of reduction in reaction with hydrogen gas in the reactor, the generation of methane is reduced, and thus carbon contamination of polycrystalline silicon is reduced.
