Abstract

The detection and quantitation of-cristobalite in quartz is necessary to calculate threshold value limits (TVL) for free crystalline silica (FCS) as proposed by the American Conference of Governmental Industrial Hygienists (ACGIH). The cristobalite standard used in this study was made by heating diatomaceous earth to the transition temperature for cristobalite. The potassium bromide (KBR) pellet method was used for the analysis. Potassium cyanide (KCN) was used as an internal standard. Samples ranged from 5% to 30% cris-tobalite in quartz. Precision for this method is within 2%.
