Vito materials technology b 2400 mol belgium. Crystalline phase evolution of the hollow alumina spheres ceramic and mullite precursor powder was followed by x ray diffraction xrd cuka source λ 0 154056 nm 6 min 10 2θ 90. The obtained fahs ceramic foams sintered at 1350 c possess high compressive strength of 33 4 mpa and bending strength of 9 6 mpa. The density of the syntactic foams is influenced by the packing arrangement of the hollow spheres.

The obtained fahs ceramic foams exhibit high porosity in the range of 73 81 which is much higher than those reported in literatures with respect to ceramic foams from hollow spheres. The process was based on the mullitization of al 2 o 3 and kaolin and the sic particles were bonded by the mullite and melted sio 2 the pores were produced by the stacking of sic particles debonding of epoxy and adding of sio 2 hollow microspheres. Ceramic hollow spheres are being developed for electronic uses in piezoelectric transducers and low dielectric constant substrates for structural applications in syntactic and metal foams for. Compared with the conventional preparation method such as dry pressing direct stack sintering and gelcasting the ceramic foams prepared by sls exhibit the highest porosity.
