High efficiency porous ceramics with controllable porosity

The increasingly growing anxiety in society about global warming and interest about construction materials which are less harmful to the environment, encourages manufactures and scientists to think about the use of more effective resources which are available and necessary for production, as well as finding possibilities and solutions for the decrease of primary energy resources depletion by producing ecological materials from local raw materials such as clay – the main raw material for the production of ceramic materials and their products, as well as more widely distributed sediments which mainly forms the upper part of the Earth’s crust. Notwithstanding the distribution of clay, the current amount of clay usage is similar to that of the second part of the ‘50s which is equal to the middle of the ‘30s of the past century. Besides traditional ceramic materials, porous ceramics has also been widely researched and is becoming a more and more popular material in the world, thanks to its wide possibilities of usage in different applications and technology industries – from construction to mechanical engineering and even cosmic applications. The chemical-mineral content, type of formation, thermal processing provisions, etc., of raw materials determines the ceramic material’s porosity characteristics. Many researchers have investigated porous ceramics with efficient properties, in order to research factors which influence the microstructure of porous ceramics, using polymer-material saturation with clay slicker and concluding how to produce porous ceramics. During the presented research porous ceramics was produced, by using a polymer material which was saturated with clay slicker. The obtaining of porous ceramics, using a foam polyurethane pump as a burnable filler, is promoted by the fact that current technology used for producing foam polyurethane allows it to form preferable porous structures within wide ranges, with pore dimensions starting from some micrometers up to 2-3 millimeters. Porous ceramic materials obtained within this research breathe; they are thermostable, resistant to thermal impacts, corrosion, and are easy to process.
