Figure 1-37 TEM image showing crystaiiized Si02-Al2 37 " 2 2 glass, heat treated to 1000 C for 45 min. p-spodumene solid solution was formed in the glass-ceramic (bar = 1 pm).

The microstructure of a typical P-spodumene solid solution glass-ceramic in the form of Corning Ware is presented in Fig. 2-6. The width of the main crystal phase of P-spodumene solid solution measures 1-2 pm.

The compositions of commercial P-spodumene solid solution glass-ceramics are shown in Table 2-8. The composition of Corning Ware differs from that of Cercor in that it contains a number of additions that Cercor does not contain. 

Beall (1992) attributes a great deal of importance to the glass matrix representing the cellular membrane in the solid-state reactions of P-quartz solid solution and P-spodumene solid solution glass-ceramics, the tenacious residual... 

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). 

Other P-spodumene solid solution glass-ceramics were developed under the trademarks Cer-Vit (Owens-Illinois) and Hercuvit (PPG) in the United States and in the United Kingdom. The latter was used to produce cooking surfaces (Pincus 1971). 

In Japan in 1962, P-spodumene solid-solution glass-ceramics were also produced on the basis of developments achieved by Tashiro and Wada (1963). The products...
