    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.

    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. Wood ash - Wikipedia

    en.wikipedia.org/wiki/Wood_ash

    Wood ash is commonly disposed of in landfills, but with rising disposal costs, ecologically friendly alternatives, such as serving as compost for agricultural and forestry applications, are becoming more popular. [11] Because wood ash has a high char content, it can be used as an odor control agent, especially in composting operations. [12]

  5. Lignin characterization - Wikipedia

    en.wikipedia.org/wiki/Lignin_characterization

    The ash content can be defined as the gravimetrically determined residue after ignition at a defined temperature, in a sample, in percent (weight / weight dry matter of sample). In the determination, a sample is weighed in a heat-resistant crucible, dried at 105±2 °C, and ignited in a muffle furnace at 525±25 °C.

    Bone ash is a white material produced by the calcination of bones. Typical bone ash consists of about 55.82% calcium oxide , 42.39% phosphorus pentoxide , and 1.79% water . [ 1 ] The exact composition of these compounds varies depending upon the type of bones being used, but generally the formula for bone ash is Ca 5 (OH)(PO 4 ) 3 .

  9. Lignite - Wikipedia

    en.wikipedia.org/wiki/Lignite

    Lignite mining, western North Dakota, US (c. 1945). Lignite is brownish-black in color and has a carbon content of 60–70 percent on a dry ash-free basis. However, its inherent moisture content is sometimes as high as 75 percent [1] and its ash content ranges from 6–19 percent, compared with 6–12 percent for bituminous coal. [5]
