DECREPITATION AND THERMAL-DECOMPOSITION OF DOLOMITE

A commercially available dolomite was split into six different particle size ranges and thermogravimetric and differential thermal analysis was performed on each of these samples. XRD was performed on each size range before TGA with no differences found. Chemical analysis was performed only on the bulk material. The particle size was found to affect the shape but not necessarily the position of the DTA curve. Decrepitation was found to be most affected by particle size. These data were evaluated in an effort to explain the decrepitation and thermal decomposition of dolomite.
