University of Hyderabad secures patent for advanced ceramic fabrication method

Hyderabad: The University of Hyderabad patented a new method for making ceramic components with complex shapes and high strength, marking a major research achievement for the institution.

The patent, granted on January 7, 2026, went to a research team led by Prof. V. Seshu Bai from the School of Physics at University of Hyderabad.

According to the researchers, the method allows the production of alumina components with nearly 99 per cent uniform density. In addition, the components showed fracture toughness of about 3 MPa√m and flexural strength close to 390 MPa.

University of Hyderabad patent offers precise ceramic manufacturing

The patented process uses gelcasting of ceramic slurries into expanded polystyrene moulds. These moulds are created using CAD-based cutting techniques.

As a result, the method ensures high precision and uniform material quality. It also allows easy mould removal and avoids damage to the ceramic body.

Moreover, the researchers said the technique is not limited to alumina alone. Instead, industries can extend it to ceramics such as zirconia and tungsten carbide.

The process also helps spread reinforcing materials evenly throughout the component. Therefore, it improves strength and overall performance.

Because of these features, the innovation has strong use potential in automobiles, aerospace, and the medical fields. This includes parts for surgical implants.

Researchers described the method as low-cost and industry-friendly. At the same time, they said it boosts the university’s role in applied research and technology transfer.

The inventors include Dr V. Seshu Bai, Dr T. Rajasekharan, Dr P. Jeevan Kumar, Mr Poly Rose, Mr Pawan Kumar Verma, and Dr A. Rajanikanth. The team represents the School of Physics and HYMOD Advanced Products & TIDE-Aspire at the University of Hyderabad.
