Century Dictionary and Cyclopedia
    • n sorbite A crystalline principle (C6H14O6) isomeric with mannite: found in mountain-ash berries. It does not ferment with yeast or reduce copper solutions.
    • n sorbite A constituent of steel; practically pearlite which has not had time to become perfectly formed. The solid solution of carbon in iron (austenite) will decompose into pearlite, together with either excess ferrite or excess cementite, according as the percentage of carbon is less or more than 0.90 per cent. The complete decomposition of the austenite requires time, and there is therefore very frequently only a partial resolution into pearlite. The transition-forms between the austenite and pearlite are called respectively martensite, troostite, and sorbite. Present knowledge does not disclose fully the nature of these transition-forms.
