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 Otherwise Known as Sheila the Great Otherwise Known as Sheila the Great is a children's novel by Judy Blume, first published in 1972. It's the second book in the Fudge Series. The book centers on Sheila Tubman, a ten-year-old girl who masks her insecurities with a much more self-assured, confident person. In truth, she suffers from fears ranging from arachnophobia (fear of spiders and other arachnids), cynophobia (fear of dogs), and aquaphobia (fear of water). Her family decides to spend the summertime in Tarrytown, New York, where she is enrolled at a day camp and meets Merle "Mouse" Ellis, an
