ABSTRACT:
A method is provided to determine the concentration of an amorphous material such as blast furnace slag in a slurry such as drilling fluid, completion fluid fluids. A sample is annealed at a temperature between about 800.degree. C. and about 1000.degree. C. for a time period of about six hours to form crystals from the amorphous material, and the sample along with a known amount of a standard is then analyzed by X-ray diffraction. This method is particularly useful in determining the amount of blast furnace slag in a drilling fluid prior to conversion of the drilling fluid to a wellbore cement slurry by addition of additional blast furnace slag.
