Obtaining Efficiency Porous Ceramics with Controlling Size of Porosity

Abstract

Anxiety of society about global warming is increasingly growing and interest about construction materials that are less harmful to the environment is growing as well. Manufactures and scientists are urged to think about the usage of more effective resources, which are available and necessary for production, as well as to find possibilities and solutions for the decrease of primary energy resource depletion by producing ecological materials. Clay is one of local raw materials that can help solving growing problems by production of ceramic materials and their products, as well as more widely distributed sediments, which mainly form the upper part of Earth’s crust. Alongside traditional ceramic materials, porous ceramics are also widely researched, becoming an increasingly popular material in the world, mainly owing to their wide possibilities of usage in different technical and technology industries – from construction to mechanical engineering, health industry and even space technology. Obtaining porous ceramics using different kind of burnable fillers, such as natural products obtained as waste from agricultural industry, as well as controllable form products obtained from polymers, allow to form desirable porous structures within wide ranges: with pore dimensions starting from some micrometers up to 2-3 millimeters. Porous ceramic materials obtained within this research are breathing, they are thermostable materials, resistant to thermal impacts, corrosion and are easy in processing. During the presented research porous ceramics were produced using different kinds of burnable fillers. The optimal burning treatment was developed for obtaining required mechanical properties of porous ceramics. The physical-mechanical properties of obtained ceramics were evaluated.
