In order to identify ways to improve the technological process of smelting metallic (crystalline) silicon of technical purity, a thermodynamic analysis of the interaction of components in the SiO2-C system is carried out that reveals the main factor in obtaining high-quality technical silicon is the elimination of superposition of the silicon carbonization process that is possible by carrying out a two-stage carbothermal reduction reaction, in that firstly the incomplete reduction of silica (SiO2) by solid carbon (C) is provided, accompanied by the release of new reacting gas components - SiO and CO, the subsequent interaction of which leads to the formation of the target product - technical silicon that is suitable for the production of modern solar energy converters. It is determined that main condition for highly efficient reduction reactions is the fine fractionness (<1 mm) of the used quartzite ore with keeping of a rational temperature range for its carbothermal reduction (1688-2000 K). It has been shown experimentally that the optimal technical solution for the implementation of this reduction process is to performt melting in a special plasma-chemical furnace-reactor with one liquid-metal subconducting electrode, with a reverse vertical feed of the reaction gases released at the first stage. The degree of extraction of silicon was on average 95%, and the degree of its purity was 97.2%.

Characteristics of chemical substances or functional groups can be presented with different signals. In general, the signal is called the parameter of the process we use to refresh, register and for transmission. There are lots of signal transmissions and processing example: Human sensory organs (visual, hearing sensations) signals the brains to provide information to the environment with different information and in the brain to process the signals and make decisions on the brain by the brain. The task of processing the signal function of the chemical substance is to identify the existing data in the signal and convert them to make a decision in a convenient form that serves the determination of the chemical compound. The signal analysis underlines not only its mathematical transformation, but also the conclusion of the conclusions of the specific processes and objects as a result of this transformation.

The sectoral priorities of science and technology determine the socioeconomic factors of the growth of states, which in turn provides for the system components of public safety. The most important components of all sectoral priorities are synergistic-hybrid technologies, i.e. such technologies that are formed in the field of inter-sectoral competence. To solve the problems of determining priorities in the field of synergistic-hybrid technology, the decisive function is the implementation of philosophical understanding of the problem, which is put forward as the main factor in decision making through the key components of sustainable development.
