Glass additives

Tantalum is used widely, although in small quantities in the electronics industry in electrolytic capacitors, emitters, and getters. The corrosion resistance of tantalum has been compared with that of glass. Additionally, the metal has a high heat-transfer coefficient and is easy to fabricate. Consequently, it finds use in equipment that must resist strong corrosive... 

At higher concentrations in frozen glasses, additional features are observed a broad, weakly structured band centred around 600 nm, and an unstructured band at 720 nm. These have been assigned to aggregated forms involving n-n and metal-metal da -n interactions, respectively [67]. In the solid state (as opposed to glasses), aggregate emission is typically observed,... 

Aluminum hydroxide is used in stomach antacids (including Maalox , Mylanta , and Delcid ), as a desiccant powder in antiperspirants and dentifrices in packaging materials as a chemical intermediate as a filler in plastics, rubber, cosmetics, and paper as a soft abrasive for brass and plastics as a glass additive to increase mechanical strength and resistance to thermal shock, weathering, and chemicals and in ceramics (HSDB 1995). Aluminum hydroxide is also used pharmaceutically to lower the plasma phosphorus levels of patients with renal failure (Budavari et al. 1989 Sax and Lewis 1987).

At least three corners must be shared. For one-component glasses, each polyhedron shares corners with at least three other polyhedra, such that the network is continuous in three dimensions. In multicomponent glasses additional cations are distributed throughout holes in the network. 

Dibutyl phthalate has multiple uses in a variety of materials. Primary uses for dibutyl phthalate are to soften and increase plastic flexibility, for example, in shower curtains, raincoats, food wraps, and car interiors to name a few. It has been used in insect repellents and as a solvent for perfume oil and resins. Dibutyl phthalate can be used as a plasticizer in nitrocellulose lacquers, elastomers, explosives, nail polish, and solid rocket propellants. Other uses include perfume fixative, textile lubricating agent, safety glass additive, printing inks, and adhesives. 

Light penetration may be greater with plastic (compared with amber glass). Additional checks advised, both with and without a carton. 

Compared to plastics, glass additives cover fewer purposes, i.e. colourants, opacifiers, decolourisers, modifiers, and stabilisers. Certain additional technical ingredients may be employed, e.g. alumina to improve durability. Coloured glass may be obtained by solution (glass acts as a solvent for certain oxides) or by colloidal dispersion the following are examples.

Y-direction. The l.e.c. values decrease not only due to the glassfibre addition the temperature dependency of the l.e.c. also decreases. The efficiency of the glass addition strongly decreases for volume percentages a 13.5 %. Figure 9.13B shows the same results but measured in the Z-direction. Both the level and the temperature sensitivity of the l.e.c. values increase in this direction due to the glassfibre addition. 

OTHER COMMENTS used in the manufacture of white metal, bullets, thermoelectric piles, medicines chemical intermediate for fire retardant compounds, ceramics, glass additives, and paint pigments. 

In the present work, the effects of glass addition, ranging from 0 to 45 wt.%, on the physical, mechanical and thermal characteristics of the clay bricks were studied. The preparation of lightweight clay bricks by using a combination of glass wastes and rice husks were also preliminary investigated.
