STATE OF THE ART Nowadays, ceramic sanitary ware is produced by casting into plaster molds and then firing. There are three important criteria that determine the quality of the ceramic product. These criteria are... The desired characteristics of ceramic clay are its composition, particle size, and firing regime. The component that provides the strength value is calcined molten metal, known as chamotte. (pre-cooked) and size-regulated semi-processed kaolin-based It is a raw material. Chamotte forms the hard skeleton of ceramics and refractories at high temperatures. It is used to create and limit shrinkage due to sintering. Chamotte is used in ceramics because it forms the skeleton of the structure after firing. It plays an important role in the production of materials. A fine fire clay (FFC) The recipe uses 35-40% chamotte. In our country, there is a domestic supplier. The raw material for chamotte, which is not available, averages 30,000 annually throughout Türkiye. There is a consumption of tons. For these reasons, chamotte is indispensable in the ceramics industry. It is the raw material. Ceramic waste is recycled and reused. Apart from its evaluation, almost all of the chamotte raw material is imported. is supplied. In current technology, the type of chamotte commonly used in our country is known as Bulgarian chamotte. It is a type of chamotte, named and imported from Bulgaria, used in the ceramics industry. This raw material used contains various ceramic minerals in different proportions. These ceramic minerals vary regionally. 2 This shows that processing kaolin means directly obtaining chamotte. No. Because chamotte is a parameter that directly affects the prescription and is 50%. It is used in ceramic recipes. Drying occurs with changes in the recipe. And shrinkage and baking values ​​can vary. This also means that the molds are changed during the production phase. This means that things are changing. Such situations occur in large commercial enterprises. Physical changes, whether raw material or design-focused, require both time and... It is not desired due to cost. In businesses that produce tons every day. A potential malfunction could cause the system to shut down and result in significant damage. Chamotte, obtained from calcined kaolin, is much denser and therefore heavier. It is a raw material. Because it is used in very high quantities in ceramic recipes, it is... The issue is that the freight cost of imported raw materials exceeds the cost of delivery to the end-use location. This results in much higher costs. This also affects the costs of the final product. This increases costs. An alternative obtained from local mines would both reduce costs. This will both lower it and contribute to reducing the carbon footprint. With the elimination of intermediary firms and regulations in the domestic product market, it truly becomes a reality. A sectoral advantage will be gained. Therefore, commercially used Bulgarian chamotte... Producing chamotte that follows the exact same chamotte recipe and provides the same macroeconomic characteristics. It has become necessary.
