Clay raw materials in international literature
and "clays" under the title of ball clay, red clays, fire clay, refractory clays and bentonite took place. By separating clay raw materials from kaolins, it would be correct to give the relevant production and reserves as "clays" instead of "ceramic clays". The ceramic industry consumes 80% of the clay and kaolin raw materials produced in the world. In a “clay-based ceramic kill, the clays that provide the shaping as well as the quartz and feldspar (melters) that form the skeleton are the basic raw materials. Since all of these basic raw materials are silicate minerals, “clay-based ceramics” are called ceramic silicate ceramics ”or“ structural ceramics de in the international literature as well as “traditional ceramics..
In parallel with the increase in population in the world and Turkey, as long as the developments in the construction sector clay-based ceramics (structural ceramics) (silicate ceramics) and will continue the importance of basic raw material, clay, and will hold the distinction of being an important raw material in each period on a continuous agenda. In parallel with the development of the construction sector, the demand for clay has increased as a result of the development of “structural ceramic” (silicate ceramics) technology in the world, which has brought many problems to producers and consumers.
Particularly in this period when negotiations for full membership to the EU will begin, the ceramics sector, which is one of the sectors that can compete in terms of production quantity and quality in European and World industries, will become a permanent and more progressive sector; We believe that the production, consumption and quality of “clays olan, the raw material of ceramics and the raw material with high consumption, will also be required by the state and many measures and studies to be foreseen. In this report, in accordance with the international terminology under the title of clay raw materials, especially clay clay figures which are the most important among clay raw materials will be given.
Plastic material, which hardens when dried and cooked, including clay minerals, is generally accepted as “clay” raw material. Generally, as a result of decomposition of igneous and metamorphic rocks by atmospheric, hydrothermal or both factors, clay raw materials are composed of kaolinite, illite, chlorite, smectite, quartz, feldspar, calcite and other non-clay minerals which are mostly clay minerals starting from feldspar minerals. As a result of this decomposition physicochemical conditions of the decomposition, the first rock minerals and decomposition products remain in place or transport and storage conditions differ with the conditions of different deposits and raw materials of different properties are formed.
