Glass-to-metal seal formation of lithium tungstate. Due to its low thermal expansion coefficient, matched to glass, tungsten is frequently used for glass-metal bonds. Tungsten forms satisfying bonds with glasses with similar thermal expansion coefficient such as high-borosilicate glass. The surface of both the metal and glass should be smooth, without scratches. Tungsten has the lowest expansion coefficient of metals and the highest melting point. 304 Stainless steel forms bonds with glass via an intermediate layer of chromium(III) oxide and iron(III) oxide. Further reactions of chromium, forming chromium silicide dendrites, are possible. The thermal expansion coefficient of steel is however fairly different from
Otherwise Known as Sheila the Great work with Sheila because of her fear of the water Judy Blume dedicated the book to her father and her mother. The post-2002 reprints of this book have some lines edited and a bit of new content added to update the technology use in it (for instance, record players are replaced with CD players, and the camp's copier keeps malfunctioning, which is why Sheila must use a mimeograph machine, whereas the original had them already still using their mimeograph machine and not having a copier yet).
