One of the most promising areas of production is additive technologies of building, in particular powder 3D printing. The aim of the work is to create a plasma-chemical method of obtaining amorphous silicon dioxide, satisfying the characteristics for the use of additive technologies of build-ing products, as well as in columns used in high performance liquid chromatography - one of the most common methods of study, as well as control of the environment and production products. One of the main requirements for particles is a porous structure with a surface that has a chemically bonded or physically coated active phase used for separation. Experimental installation for obtaining amorphous silica was developed, the feature of which was the possibility of rapid and continuous supply of pressed briquettes, rather than powdered material as it was previously. Studies have shown that the developed plasma-chemical process implemented in the condition of evaporation of briquettes consist-ing of 70% sand and 30% coke is effective enough to produce silicon oxide nanoparticles smaller than 200 nm. The developed method of obtaining nanoparticles should be further investigated on the ability to obtain nanoparticles smaller than 20 nm, it is so necessary to obtain the specific surface area of 200 m2/g, which will make it possible to produce from this raw material particles of the fixed phase carrier column of high-performance liquid chromatography.
