  2. Ash (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Ash_(chemistry)

    A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.

  3. Ash - Wikipedia

    en.wikipedia.org/wiki/Ash

    Ash is the solid remnants of fires. [1] Specifically, ash refers to all non- aqueous , non- gaseous residues that remain after something burns . In analytical chemistry , to analyse the mineral and metal content of chemical samples , ash is the non- gaseous , non- liquid residue after complete combustion.

  4. Loss on ignition - Wikipedia

    en.wikipedia.org/wiki/Loss_on_ignition

    For example, the loss on ignition of fly ash is composed of contaminants and unburnt fuel. In pyroprocessing industries such as lime,calcined bauxite, refractories or cement manufacture, the loss on ignition of the raw material is roughly equivalent to the mass loss it will experience in a kiln. Likewise, in minerals, the loss on ignition ...

  5. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    Since the heat of combustion of these elements is known, the heating value can be calculated using Dulong's Formula: HHV [kJ/g]= 33.87m C + 122.3(m H - m O ÷ 8) + 9.4m S. where m C, m H, m O, m N, and m S are the contents of carbon, hydrogen, oxygen, nitrogen, and sulfur on any (wet, dry or ash free) basis, respectively. [8]

  6. Arsinide - Wikipedia

    en.wikipedia.org/wiki/Arsinide

    An arsinide, arsanide, dihydridoarsenate(1−) or arsanyl compound is a chemical derivative of arsine, where one hydrogen atom is replaced with a metal or cation.The arsinide ion has formula AsH − 2.

  7. Particle-size distribution - Wikipedia

    en.wikipedia.org/wiki/Particle-size_distribution

    It can be measured for any fluid system with no dilution or other sample preparation. This is a big advantage of this method. Calculation of particle size distribution is based on theoretical models that are well verified for up to 50% by volume of dispersed particles on micron and nanometer scales.

  8. Arsine - Wikipedia

    en.wikipedia.org/wiki/Arsine

    In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]

  9. Electrostatic precipitator - Wikipedia

    Condensation and adsorption on fly ash surfaces. May also increase cohesiveness of fly ash. Reduces resistivity. Ammonia: Mechanism is not clear, various ones proposed; Modifies resistivity. Increases ash cohesiveness. Enhances space charge effect. Ammonium sulfate: Little is known about the mechanism; claims are made for the following:
