INCREASİNG THE ABRASİON RESİSTANCE OF FLOOR TİLES BY USİNG NATURAL BONE POWDERS

Ceramic tiles are subjected to constant compression and abrasion. Since ceramic materials are brittle, the surfaces of porcelain tiles are subject to continuous abrasion and deterioration of surface properties. In order to reduce this deterioration observed on the porcelain tile surface, a study was conducted to increase the abrasion resistance of floor tile glazes using natural animal bones. Natural animal bones were ground in the range of 38-45 microns and added to the floor tile glaze recipe at a rate of 1-8% by weight and applied to floor tile glazes. While the reinforced bone powders do not cause a significant increase in the viscosity of the glaze, they cause a more matte appearance. These samples were sintered at 1070 oC, prepared in 2X2cm2 sizes and their mechanical wear properties were investigated. Abrasion tests were carried out on a ball disc abrasion tester in a dry environment without oil and at room temperature. Abrasion tests were carried out at a sliding speed of 0.3 m/s, under a load of 5 N and 50-100 meters in length. The abrasion resistance increased by about 20% compared to the specimens without bone dust. As a result of the abrasion test, microstructure properties were analyzed by scanning electron microscopy (SEM) and X-ray energy dispersive spectroscopy (EDS). Surface distortion values and wear volume ratios of bone powder additives were measured with Taylor-Hobson Rugosimeter Surtronic 25 device. As a result of the destructive tests, It was found that the resistance to abrasion of porcelain floor tile glazes increased with the increase in bone dust content.
