The present experimental thesis examines the changes in the structures and mechanical properties of ceramic substrate membranes using kaolin, calcium carbonate, and hydroxyapatite, depending on the firing temperature and the quantitative ratio of each material. Ceramics are formed by a uniaxial compression method. Ceramic substrates are fired at four different temperatures. Through the analyses conducted before and after firing, the evolution of the specimen properties, such as pore size, porosity, and strength can be observed. The objective is to evaluate the effect of different contents of kaolin, calcium carbonate, and hydroxyapatite on the properties of the specimens for different firing temperatures. The work resulted in ceramic substrate membranes that could be used for microfiltration. The presence of hydroxyapatite appears to significantly improve the porous structure and mechanical properties of the produced ceramics. The substrate with a composition of 20 % CaCO3 and 5 % HAp achieved a maximum strength of 42 MPa at a firing temperature of 1400 °C.
