Pushing the boundaries of traditional ceramic techniques

In recent years, scientists have been adding graphene oxide (GO) to ceramic slurries -- consisting of particles of kaolin clay or other materials dispersed in water -- to make fired ceramics more durable and resistant to thermal shock. Materials scientist Daria Andreeva and colleagues adapted this technique by using ultrasound to better mix the GO into kaolin slurries. They adjusted GO concentration and ultrasound exposure time to find the conditions that most enhanced the resulting ceramics' strength and heat resistance. The team also collaborated with artist-in-residence Delia Prvački,, who created works from the new ceramic material that are on display at the National University of Singapore Museum.

"We explored artistic potential by experimenting with novel ceramic forms and textures," the study's authors note. "Harnessing the properties of graphene pushes the boundaries of traditional ceramic art, enabling the creation of delicate and intricate ceramic structures that were previously unattainable. This approach not only enhances the artistic possibilities but also can potentially reduce the need for structural elements."
