White glass-ceramics

Neoceram N-11 glass-ceramic are shown in Table 4-11. Because of these properties, this white glass-ceramic can be used in a number of consumer-oriented applications, including flat, smooth products such as stove tops, hot plates in microwave ovens, or the inner cladding of microwave ovens. At the same time, however, it is possible to produce glass-ceramics of curved or almost any desired shape (Wada 1998).

In addition to Neoceram N-0, Nippon Electric Glass Co., Ltd., also produces another glass-ceramic that demonstrates zero expansion. Neoceram N-11 is a white, nontransparent glass-ceramic that contains P-spodumene solid solution primary crystals measuring approximately 1 pm. This glass-ceramic is used for induction cooker top plates, Kitchenware, (Section 4.2.1) or for optical components, such as the coupler housings of optical fibers (Neoceram 1992, 1995). 

Another route to stable high-reflectance standards is the use of ceramic tiles or white glass materials. Such materials are usually used only in the visible region of the spectrum due to absorbances shown by the pigments in the UV and NIR. Typically, the tiles are a ceramic baked onto a metallic substrate, with the white pigment usually being titanium dioxide. Such standard materials are provided by Erie Ceramics and the OMH. These standards are used heavily in the color measurement instrumentation in which durability is the key factor in their selection. A similar standard, under the appellation of SRM-2019, has been provided by NIST for use in the...
