Abstract
Monolithic boron suboxide ceramic was densified by microwave sintering at 28 GHz using highly stoichiometric B6O powders. High heating rate of 200 °C min−1 was maintained owing to special insulation cell which acts as additional microwave absorber. This insured homogeneous heating during sintering and resulted in dense and crack-free specimens. Room-temperature strength and fracture toughness of bulk B6O ceramics were as high as 400 MPa and 2.8 MPa m1/2, respectively.
