Inert atmospheres consisting of gases such as argon, nitrogen, or helium are commonly used in chemical reaction chambers and in storage containers for oxygen-or water-sensitive substances, to prevent unwanted reactions of these substances with oxygen or water. [4] Argon is widely used in fluorescence tubes and low energy light bulbs.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Because of that, amorphous materials have a characteristic threshold temperature termed glass transition temperature (T g): below T g amorphous materials are glassy whereas above T g they are molten. The most common applications are in the making of pottery , glass, and some types of food, but there are many others, such as the vitrification of ...
Uses of fibreglass include building and construction materials, boat hulls, car body parts, and aerospace composite materials. [92] [89] [91] Glass-fibre wool is an excellent thermal and sound insulation material, commonly used in buildings (e.g. attic and cavity wall insulation), and plumbing (e.g. pipe insulation), and soundproofing. [92]
The walls of glass ampoules are usually sufficiently strong to be brought into a glovebox without any difficulty. Glass ampoules are more expensive than bottles and other simple containers, but there are many situations where their superior imperviousness to gases and liquids and all-glass interior surface are worth the extra cost.
C-glass was developed to resist attack from chemicals, mostly acids that destroy E-glass. [10] T-glass is a North American variant of C-glass. AR-glass is alkali-resistant glass. Most glass fibers have limited solubility in water but are very dependent on pH. Chloride ions will also attack and dissolve E-glass surfaces.
For example, if you leave an open glass of water next to coffee, the water will smell a bit like coffee the next day, even if it doesn’t make any contact. ... Related articles. Show comments ...
The structure of liquids, glasses and other non-crystalline solids is characterized by the absence of long-range order which defines crystalline materials. Liquids and amorphous solids do, however, possess a rich and varied array of short to medium range order, which originates from chemical bonding and related interactions.
