Research on the Synthesis and Application of Mullite and Mullite–Corundum Ceramic Pigments Obtained from Pure and Waste Raw Materials

The project aims to develop and investigate new mullite and mullite–corundum pigments using both pure and waste raw materials – rice husks and industrial catalysts. The main focus is on optimizing the synthesis conditions and the properties of the obtained materials, applying solid-state sintering and sol–gel methods. Various chromophore ions (Co, Cu, Ni, Cr, Fe, Mn) and their influence on the structure, composition, and color properties of the pigments are examined.

Main scientific activities include:

• Comparative analysis of pigments synthesized from pure and waste raw materials;

• Use of advanced analytical methods for characterization (X-ray diffraction, IR spectroscopy, EPR, electron microscopy, etc.);

• Application of waste catalysts and rice husks for environmentally sustainable pigment production;

• Assessment of the potential for industrial implementation.

Expected results:

• Advancement of scientific knowledge in the field of ceramic pigments and sustainable waste utilization;

• Publications in prestigious scientific journals and participation in international conferences;

• Strengthening the research capacity of participating universities through the training of young scientists, including doctoral candidates and students;

• Development of an innovative and environmentally oriented technology with potential for industrial application.

The project is jointly implemented by:
Burgas State University “Prof. Dr. Asen Zlatarov” (lead organization) and Ruse University “Angel Kanchev” (partner). The scientific supervisor is Prof. Dr. Irena Georgieva Markovska, who has extensive experience in managing scientific projects.
