Probing into the potential features of sodium calcium silicate (Na2Ca2Si3O9) synthesized by the solid-state route

Abstract

Abstract Silicate ceramics are one of the established candidates employed in many industrial and medical applications. Not many of the existing reports mention and investigate the properties of the phases or individual components of these materials. In this exploratory study, one such sodium calcium silicate, combeite (Na2Ca2Si3O9) was synthesized by the solid-state route and studied for its properties. The preliminary investigation involved thermal treatments followed by characterization to identify the formation of the pure phase. The mechanical behaviour was evaluated by compression tests. Surface treatments were executed to enhance the capabilities to support cellular proliferation. The in-vitro acellular immersion test showed the formation of calcium phosphates. All the tested materials exhibited adequate cell viability properties for prospective applications in life sciences.
