delayed onset of quicklime hydration |
| abstract |
The present invention provides compositions and methods for controlling the onset of hydration of an alkaline earth metal oxide such as calcium oxide, comprising heating an inorganic alkaline earth metal oxide to subcalcination temperatures in the presence of organic material comprising a carbohydrate, an amino carboxylic acid, a hydroxy carboxylic acid or a mixture thereof. Preferred treated particles comprise at least 40% and more preferably at least 80% by dry weight of calcium oxide which is heated in the presence of ascorbic acid and a starch. Treated particles of the present invention exhibit surprising and unexpected hydration-inducing postponement behavior as demonstrated by the calorimetric test. |
