Boron trioxide or diboron trioxide is the oxide of boron with the formula B 2 O 3. It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty.
Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Other elements, like aluminum and beryllium, have even higher energy content than carbon, but do not mix well to form a stable fuel that can be easily burned. [1] Of all the low-mass elements, boron has the combination of high energy, low weight and wide availability that makes it interesting as a potential fuel. [1]
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
Trioxidane (systematically named dihydrogen trioxide, [2] [3]), also called hydrogen trioxide [4] [5] is an inorganic compound with the chemical formula H[O] 3 H (can be written as [H(μ-O 3)H] or [H 2 O 3]). It is one of the unstable hydrogen polyoxides. [4] In aqueous solutions, trioxidane decomposes to form water and singlet oxygen:
Although boron is a relatively rare element in the Earth's crust, representing only 0.001% of the crust mass, it can be highly concentrated by the action of water, in which many borates are soluble. It is found naturally combined in compounds such as borax and boric acid (sometimes found in volcanic spring waters).
Boron oxide may refer to one of several oxides of boron: Boron trioxide (B 2 O 3, diboron trioxide), the most common form;
Cerium oxide finds use as a fuel additive to diesel fuels, [clarification needed] which results in increased fuel efficiency and decreased hydrocarbon derived particulate matter emissions, [6] however the health effects of the cerium oxide bearing engine exhaust is a point of study and dispute.
