Synthesis and characterization of zirconia–magnesia inert
· The dry precipitate was then ground by mortar and pestle to a powder before being calcined at 700 °C overnight in air to convert it to the oxide. The oxide powder was cold pressed to 500–600 MPa with a SPEX Carver hydraulic press in a SPEX 5 mm die to produce green pellets.

Template-free preparation of humidity self-regulating
· In this work a silica-based mesoporous oxide (SMO) was directly fabricated via a template-free method using the abundant and inexpensive volcanic ash as raw material. By alkali hydrothermal activation and acid hydrothermal etching of volcanic ash the SMO with large mesopore size (7.94 nm) high specific surface area (459.5 m2/g) and total pore volume of 1.05 cm3/g was produced.

The effect of cement composition and pH of environment on
· The difference in behavior of the other cements was less noticeable in low pH sulfate solution. Generally the acid type attack on hardened cement pastes is associated with ero- sion and softening due to leaching of Ca and dalcification of C-S-H.4 Hence expansion might be expected to be less with reducing pH level.
