The investigation is primarily concerned with a study of the effect of petalite additions on the thermal expansion behavior of ceramic bodies. The behavior of bodies which are most easily formed by adding petalite to clays or kaolin, is illustrated. The results show that clays with a low ...
As the lightest metal element, the structure and properties of lithium attract the interest of researchers. Thirty years ago, as Mahi et al. said, the discovery of lithium brought many challenges to the industry at that time, similar to the discovery of aluminum a hundred years ago [2]. ...
Considerabledisagreement exists in the literature about the terminology used for theintermediate and final phases of this transformation and for this reason the phasesare referred to in this study according to their structure. An importantcharacteristic of the hexagonal and tetragonal phases is their ...
The final phase and coefficient of thermal expansion of the fired petalite-clay and eucryptite-clay samples were examined according to changes of the mixing ratio and firing temperature. In the petalite-clay samples, lithium alumina silicate (Li2O center dot Al2O3 center dot 7.5SiO(2)) and...
