Abstract

"Impervious petalite bodies were formulated from petalite, lithium aluminosilicate frit and kaolin. Thermal expansion coefficients for selected bodies were less than 2 x 10⁻⁶ /°C(20 - 600 °C). Mineralogy and the reactions in systems containing petalite, lithium aluminosilicate frit and kaolin were observed. Silica-poor high quartz solid solution was found to be the reaction product formed from the reaction between frit and kaolin before conversion to ß-spodumene solid solution at higher temperatures. The crystallization of the ß-spodumene solid solution phases in this system did not occur at the same temperature resulting in variation in the size of the crystallites. The body containing the highest concentration of kaolin appeared to be composed of the ß-spodumene solid solution of different compositions. Closed pores were observed in impervious bodies due to the dehydroxylation of kaolin and the entrapment of gaseous decomposition product. Thermal expansion data and curves for various reacted mixes are presented"--Abstract, page ii.
