A new processing route for the manufacture of cellular glasses has been developed. The strategy adopted for making the cellular glasses entails the following steps: (i) fabricating a formed body by combining glass powder and glass microspheres, and (ii) sintering the formed body. By controlling the sintering temperature and the microsphere content, it was possible to adjust the porosity so that it ranged from ∼42% to ∼62%. The compressive strengths of the cellular glasses with ∼42% and ∼60% porosities were ∼150 and ∼60 MPa, respectively. The superior compressive strengths were attributed to the homogeneous distribution of small (≤35 μm), spherical cells with dense struts in the cellular glasses.
