In the last few years, our domestic ceramics industry has steadily increased production volumes of high-quality product, demand for which has been growing continually. However, the industry has more than a few problems, whose solution largely depends on the consolidated actions taken by specialists within the ceramics industry, suppliers of raw materials and equipment, as well as, of course, the efforts of industry scientists. This made the next scientific and applications conference topical and timely.The questions which are of greatest importance to the ceramics industry were examined at the conference: improvement of the production of ceramic articles, new domestic and imported equipment, reconstruction and upgrading of operating facilities.
The conference participants devoted a great deal of attention to questions concerning raw materials -expansion of the raw materials base for the production of ceramics, providing ceramics works with high-quality raw materials, new technologies for preparing raw materials, and utilization of technogenic wastes. This conference was of great interest for those working in the industry, scientific -research and design organizations, and equipment developers, and raw materials suppliers.The utilization of technogenic wastes, first and foremost, wastes produced in the mining and reprocessing industries, and precipitates from biological purification of sewage at aeration plants in cities and waste water from works producing large quantities of building materials, such as ceramic bricks and cement, can provide a solution to acute ecological and technical problems in the building materials industry.
The wastes from the production of glass fiber can be used not only to solve a serious ecological problem but also to increase the quality of construction ceramic articles produced at brick manufacturing plants.
The physicochemical and process properties of oversanded argillaceous raw materials and technogenic wastes from production of propylene were investigated. The process parameters of production of construction ceramics based on them are reported.The problem of providing the population with quality and moderately priced housing has now arisen. Without an important increase in production volumes and expansion of the assortment of energy-efficient ceramic construction materials, it will be impossible to solve this problem. Increasing production volumes for such materials is unconditionally correlated with a search for new kinds of raw materials. We investigated the possibility of using previously unclaimed aluminum-containing chemical plant wastes and universally distributed local oversanded argillaceous raw materials.Weak clays from the Koshchakovo and Petrovsk deposits with a free quartz content of up to 65% were used as the silica raw material for manufacturing the ceramic. This raw material sinters poorly and the samples are insufficiently strong after sintering. For this reason, addition of such an important component as alumina, Al 2 O 3 , to the ceramic paste should improve these properties as the physicomechanical properties of calcined ceramics are essentially a function of the amount of alumina. Using aluminum-containing chemical plant wastes containing CaCO 3 in addition to Al 2 O 3 was proposed.Isopropylene production wastes are a loose grey mass with a volume mass of 0.85 g/cm 3 and the following chemical composition (% in matter calcined at
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
