摘要:
The invention relates to a method for producing silicon nitride (Si3N4). According to the inventive method, nitrogen and/or nitrogen compounds are reacted with silicon and/or silicon compounds in a reaction chamber with the aid of a subgroup element or subgroup element oxide. Said method has a simple and rapid course that results in a high yield.

The invention relates to a method of driving a shaft by reaction of silanes, preferably silane oils, with air in a double combustion chamber and an associated drive mechanism. The hydrogen of the silanes reacts in the first combustion chamber with an insufficient level of oxygen of the air supplied, thereby producing high temperatures. At said high temperatures, the nitrogen from the air supplied reacts with the silicon of the silane to form silicon nitride. The resultant combustion gases and dust and the non-combusted hydrogen are mixed in the second combustion chamber with a large quantity of cold compressed air, the hydrogen undergoing late burning, and they subsequently enter a turbine chamber to actuate turbine blades connected to a shaft. The method is particularly environmentally-friendly since no toxic or polluting waste gases are produced.

The invention concerns a method for powering a drive, especially the drive of a missile or a drive of a shaft. According to said method, nitrogen and/or nitrogen compounds are reacted with silicon and/or silicon compounds in a reaction chamber with the aid of an element of the subgroup or an oxide of the element of the subgroup and silicon nitride is formed. The energy released during said reaction is used to power the drive.

The description relates to a process and a device for drilling holes in hard rocks like granite, in which the rock to be drilled is exposed to a flame produced by gaseous hydrogen and fluorine together and the reaction products produced by the flame are taken out of the drilling with the aid of a sucked aqueous liquid. In order to be able to implement the process economically while preventing the formation of toxic and corrosive reaction products, the aqueous liquid used to remove the reaction products formed is a lye, e.g. a sodium hydroxide solution, in which the excess hydrogen fluorine formed during the combustion of hydrogen and fluorine is converted into a non-toxic fluoride, e.g. sodium fluoride, while at the same time the other reaction products are converted into water-soluble silicates, aluminates and alkaline fluorides. In order to recover the very expensive gaseous fluorine used, the dissolved sodium fluoride formed by chemical reaction is converted into insoluble calcium fluoride with the aid of calcium oxide or calcium hydroxide and subsequently electrolysed.

Disclosed is a discus-shaped aerodynamic vehicle (100) intended for use at extremely high velocities and extreme altitudes and suitable for use as a long-haul aircraft. The aerodynamic vehicle is provided in its peripheral region with a reaction engine for generating vertical motion and on its underside with at least one rocket engine for generating horizontal motion. The rocket engine is in the form of a nitrogen burner in which silicon-hydrogen compounds undergo combustion at high temperatures with atmospheric nitrogen in the presence of atmospheric oxygen which serves as the oxidant for the hydrogen in the silicon-hydrogen compounds.

The description concerns a process for operating a reaction-type missile propulsion system and a propulsion system for implementing the process. The propulsion system is operated by causing silicon hydride compounds to react with nitrogen and/or nitrogen compounds at high temperatures in the presence of an oxidising agent for the hydrogen of the silicon hydride compounds. The nitrogen and the oxidising agent can be preferably taken from the earth's atmosphere, thus avoiding having to carry the oxidising agent for the silicon hydride compounds in the missile. The silicon hydride compounds burned are preferably silanols.
