Nonsilicate

Non-SI (unacceptable and obsolete) units, l xxiv-xxv 2-26 xxii-xxiii Nonsilicate crystals, glass-ceramics based on, 12 641-642... 

The crystal structures of all the minerals in the serpentine group contain the same basic building blocks. The basic unit is composed of a silicate sheet of composition (Si205) ", in which three of the O atoms in each tetrahedron are shared with adjacent tetrahedra (Fig. 2.2A), and a nonsilicate sheet of... 

MMVF are synthetic fibers with glasslike structures. The term usually refers to silicate-based glass fibers, because these compositions form the largest volume of fibers produced. However, in addition to fiberglass and fused silica (Si02), there are other amorphous fibers used in commerce alumina (AI2O3) and silica combinations, rock and slag wool, as well as fibers with nonsilicate compositions such as carbon. Many of these amorphous fibers have proprietary names. 

Other elements, such as Ga and Ge, can substitute for Si and A1 in the zeolitic framework, and there are claims that many other elements can also do so. New classes of nonsilicate zeolite-type crystalline aluminophosphates (31) and silicoaluminophosphates (SAPO) (65) have been reported but relatively little is known about their chemical behaviour. 

Oxy)(hydr)oxide compounds Nonsilicate, crystalline, or amorphous solids that contain oxide (O2-), hydroxide (OH-), or oxyhydroxide (OOH3-) as the major anion. Common cations include aluminum, iron(II), iron(III), or manganese. 

This volume has just such a purpose. The first few chapters review the silanes and their derivatives in some detail, in order to provide an understanding of the fundamental chemistry of the nonsilicate compounds of silicon. The later chapters emphasize the silicone polymers which have achieved commercial importance and deal with the methods for their preparation, their chemical and physical properties, and their possible uses. The processes available for large-scale production are treated separately, and a review of methods of analysis is included. In order not to burden the text with definitions and explanations of nomenclature which might already be familiar to some readers, an extensive glossary of terms is appended. 

Wagh and Jeong [4] have reported that, once the metal ions are dissociated and screened in an acid solution that is rich with phosphate anions, the kinetics of transformation to a CBPC is very similar to that of the conventional sol-gel process of fabricating ceramics of nonsilicates [4] with the major difference here being that the acid-base reaction used in forming CBPCs carries the mixture all the way to the formation of ceramics, while in the sol-gel process the sols are ultimately sintered to form superior ceramics. Figure 5.1 illustrates the step-by-step kinetics of the formation of CBPCs. 

The synthesis of aluminophosphate molecular sieves in 1980s represents a breakthrough in the development of microporous materials. Since then, much of the worldwide synthetic efforts have been directed toward nonsilicate microporous materials. Many novel framework topologies could be found with phosphates, and many other elements could be incorporated into phosphates to produce additional new framework topologies or new compositions. 

Combination nonsilicate peroxide stabilizer and detergent for peroxide bleaching. 

Nonsilicate peroxide bleach bath stabilizer. Effective in both continuous and batch processes, PEROWHITE TW allows bruise-free, full bleached fabric without characteristic silicate buildups. 

Nonsilicate peroxide bleach stabilizer for batch processing. 

The so-called non-silicate minerals consist of a variety of different mineral groups each named for a particular anion. Only a few of these minerals contribute much volume to Earth s crust, but many of them are very important minerals for manufacturing and other industrial uses. Most mineralogists recognize ten or so major nonsilicate groups and a variable number of lesser groups. Table 2 lists several of the major non-silicate groups.
