UoH Team Patents Ceramic Manufacturing Process
A team of researchers from the University of Hyderabad has created a new way to make strong ceramic parts with complicated shapes.
Normally, making these shapes can cause cracks and weak spots, but their method ensures the parts are strong and uniform all the way through.
They use a special process called gelcasting with polystyrene molds to achieve this.
The parts they make are almost 99% uniform in density, which is important for things like car parts, airplane components, and even medical implants.
The process is also cost-effective and can be used for different types of ceramics.
This invention could help factories make better ceramic parts with fewer defects.
UoH team granted Indian patent for manufacturing high-strength ceramic components with complex shapes.
Process ensures uniform density and strength, addressing issues with conventional ceramic manufacturing.
Method uses gelcasting of ceramic slurries inside expanded polystyrene molds created from computer-based designs.
Alumina components achieve 99% uniform density, suitable for demanding applications in automobiles, aerospace, and medical implants.
Process is low-cost, reproducible, and can be extended to other ceramics like zirconia and tungsten carbide.
