A heat-resistant textile gasket and method of making it are described. The gasket has a knit, tubular body, constructed, at least in part, from non-metallic, heat-resistant yarns. It also may include metallic yarn. A jersey knit pattern for the yarn is described in order to provide optimum density.
A theoretical procedure was developed with the aim of obtaining an estimation of the crystallisation fraction in glass-ceramics by means of thermal expansion measurements. The theoretical model was applied to the crystallisation of an iron rich glass composition yielding magnetite and pyroxene as cr
The linear thermal expansion coefficient, a, has been measured from 2 to 32 K and from 55 to 90 K for a machineable glass-ceramic, an "ultra-low expansion" titanium silicate glass (Coming ULE), and ceramic glasses (Cer-Vit and Zerodur), and for glassy carbon, a is negative for the ultra-low expansio
