Chemical Composition: Cov khoom tseem ceeb yog calcium carbonate (CaCO₃). Siab purity feem ntau qhia tau hais tias zoo dua. Nws kuj tseem yuav muaj me me ntawm impurities xws li magnesium oxide, silicon dioxide, thiab hlau oxide.
Lub cev muaj zog:
Xim: Feem ntau yog dawb lossis tawm -dawb; siab purity hmoov yuav ua tau dawb huv.
Hardness: Mohs hardness yog kwv yees li 3, qhia txog kev ntxhib los mos.
Qhov ceev: Tej qhov ceev yog kwv yees li 1.2-1.5 g / cm³.
Chemical Properties:
Thermal Decomposition: Decomposes ntawm qhov kub siab (txog li 900 degree) los tsim cov kua qaub (CaO) thiab carbon dioxide (CO₂).
Acid Resistance: Reacts nrog cov kua qaub uas muaj zog los tsim cov calcium ntsev, dej, thiab carbon dioxide. Qhov no yog lub hauv paus ntsiab lus tom qab nws siv hauv flue gas desulfurization.
Acidity / Alkalinity: Aqueous daws yog qaug zog alkaline.
