The paper introduces plasma technologies developed at the Department of Applied Mechanics and Materials Science (TSUAB, Tomsk, Russia). These include processing techniques for silica glass, microspheres, protective-decorative coatings silicate materials using low-temperature plasma. effect on is described in this paper.
The paper presents the investigations on producing spherical particles 65-110 μm in size using energy of low temperature plasma (LTP). These are based flow ash produced by thermal power plant Seversk, Tomsk region, Russia. obtained have no defects and characterized a smooth exterior surface. test bench is designed to produce these particles. With due regard for field distribution, it shown that transition fly state viscous occurs at 20 mm distance from jet. X-ray phase analysis carried out...
This article is devoted to research possibility of high-temperature silicate melts producing from feldspar wastes molybdenum ores enrichment (Khakassia) with use low-temperature plasma energy.
An experimental setup is developed to create a protective and decorative coating on the surface of building materials. Experimental study conducted using low-temperature plasma. The properties before after plasma treatment are investigated. At increase generator power (56-75 kW) rate vitreous formation significantly reduced, destruction hydrous calcium silicates occurs at lower depth (0.5-2.0 mm). In this case, adhesive strength increases up 2.34 MPa. exposure time 56 kW (0.045 m/s melting...
Among silica-based materials vitreous silica has a special place. The paper presents the melting process of quartz particle under conditions low-temperature plasma. A mathematical model is designed for stages in experimental plasma-chemical reactor. As calculation data show, particles having radius 0.21≤ rp ≤0.64 mm completely melt at W = 0.65 l/s feed rate depending on Nusselt number, while 0.14≤ ≤0.44 1.4 l/s. Calculation showed that 2 and 0.4 melted during 0.1 s respectively. Thus, phase...
Low temperature arc plasma was used to process building surface materials, such as silicate brick, sand lime concrete and wood. It shown that materials modification with low positively affects frost resistance, water permeability chemical resistance high adhesion strength. Short time processing is rather economical than traditional thermic methods. Plasma makes wood uniquely waterproof gives operational properties, dimensional geometrical stability. also increases compression decreases inner...
The paper presents the data of structural studies synthesized β-SiAlON using plasma-chemical method and self-propagating high-temperature synthesis (SHS). It was found that these two methods are used to obtain with composition Si5AlON7. possibility obtaining by a plasma generator is shown. To analyze features compounds structure, parameter proposed determined ratio sum number Si Al atoms N O included in unit cell.
