Titanite, CaTiSi05 (C2/c), may incorporate Na+, REE3+ and minor ACT in the Ca site, and Fe3+, Al3+, Nb5+ in the Ti site. The ThOz content of natural titanite may reach 0.28 wt% (Hayward 1988). Measured isomorphic capacities of titanite with respect to U4+, Pu4+, Pu3+, Hf4+, and Gd3+ are (in atoms per formula unit) 0.02-0.05 (Vance et al. 2000) or 0.07 (Stefanovsky et al. 2000b) 0.02 0.05 0.5 0.3 (Vance et al. 2000) or 0.25 (Stefanovsky et al. 2000b), respectively. Due to limited solubility of ACTs and REEs in the structure, titanite is preferably considered as a host phase for these elements when their content is low, such as in titanite-based glass-ceramics developed for Canadian waste (Hayward 1988).

There have been a variety of uses of microwave ovens in the laboratory these include the processing of ceramics, development of various plastics, catalysis, and acid dissolution of various materials.3 One developing use of microwave ovens is the drying of samples for weighing.3-6... 

Look at the Japanese. Their project is based on the old superconductors, and what they re saying is that should the new ceramics develop to the level of being used, they ll simply substitute them. They have a lot of confidence that they can do the engineering work with the old superconductors, as I do. They ve studied what we did, ad nauseam. They ve been out to visit, as they al-...

In modem science, ceramic is used in various aspects. Besides this ceramics developed on the basis of clay have some special uses such as stmctural building materials, refractory materials, non-stmctural products, stmctural products, earthen ware, stone ware, porcelain, and technical ceramics. The products of ceramic materials are known to us as bricks, terra cotta, flue lining, cement-clinker, chemical ware, refractory ware, table ware, tiles, sanitary ware, insulators, split bricks, quarry tiles, acid-resistant bricks etc.

The potential range of glass ceramic compositions is fairly broad because the method depends only on the ability to form a glass and to control its crystallization. However, almost all glass ceramics developed so far are based on silicate glass compositions. They include...

After this salutary beginning, is it worthwhile pursuing the question of how hard a ceramic is Yes, because the attempts at answering this question have followed several routes that shed light on ceramic development. Figure 1.1 is a flow chart of the development of the subject that should make it clear how the topics in this book are grouped for study.
