<jats:p>In this study, five foamed ceramics with struts containing needle-like
mullite were prepared by direct-foaming method using white clay, industrial
alumina and microsilica powder as raw materials. The effects of microsilica
content on the phase compositions, microstructures and properties of foamed
ceramics were investigated. The results showed that the adding of
microsilica decreased the average pore size and apparent porosity and
increased the compressive strength and thermal conductivity of the foamed
ceramics by affecting the properties of foamed slurry and reaction sintering
process. The foamed ceramics with 10 wt.% microsilica content showed the
best properties with high porosity of 75.8%, positive reheating linear
change, compressive strength of 1.44MPa and low thermal conductivity of
0.219W/(m?K) (at 350?C).</jats:p> |
