Ancient engineering : selective ceramic processing in the Middle Balsas Region of Guerrero, Mexico
Previous experimental research into ancient pottery production has proven that potters can produce vessels with varying materials properties, such as thermal shock resistance and permeability. These properties are differentially useful for certain tasks, such as cooking or water-cooling. In certain …

Processing-composition-structure effects on the optical band gap of KNbO3-based ceramics
… which maintain the compositions stoichiometric. Ceramic processing of KNbO3 by conventional route was optimised in order to minimise K losses, which leads to the formation of a hygroscopic secondary phase, K4Nb6O17. This phase impairs the structural integrity of the samples. In addition, …

Fabricating Complex-Shaped Components by Room-Temperature Injection Molding of Aqueous Ceramic Suspension Gels
<p>Water-based ceramic suspension gels (CeraSGels) effectively produced dense, near-net shape ceramic parts by room-temperature injection molding, a novel processing method based on traditional ceramic injection molding. This alternative method eliminated the need for heating and cooling feedstocks …
