April 12, 2013, Nippon Electric Glass Co., Ltd. (NEG) announced that it has successfully developed a glass, this coefficient of thermal expansion of the glass is almost zero (the product name of this glass is ZERO ? Zero ? is significantly closezero than a conventional product. zERO ? is not because of changes in temperature and to expand or shrink, regardless of temperature changes much, almost no size change can provide zERO ? in sheet and block, there is a wide range of application and use can be expected to zERO ?range, many products will be able to use to the ZERO ? including optical communications, machine tools, such as precision scales and various parts of the material, these products require a high concentration of thermal dimensional stability. Zero ? is undoubtedly the best choice. NECglass Co., Ltd. (NEG) will actively promote zero-developed applications, and quickly launch the product on a commercial basis.
