Abstract |
Investigations have been conducted in an effort to develop rapid reliable methods for analysis of reacted limestone and limestone slurries. In this area new thin film infrared cells have been developed and demonstrated. The cells developed were then used to obtain calibration curves for species of interest in several solvent systems which would be of use in analyzing either reacted solid limestones or limestone slurries. In another phase of this program, a study was made of the influences of impurities on the dead-burning of limestone. Specifically, a study using infrared spectroscopy, electroprobe investigations and auger spectroscopy revealed both the occurrence of chemical reactions between lime and limestone and impurities at higher calcination temperatures and diffusion of impurities to surfaces and into pores.
