a soil sample taken from and pld abbey, the soil sample where taken from a room that have a blast-furnace in it, while an x-ray fluorescence gave a concentration of 1.5% of fluor, and an analysis of x-ray diffraction gave rise to the fluorapatite species, so my question how can we explain or how can we demonstrate the formation of fluorapatite in the soil sample
Have you considered the possibility that bones were calcined in the kiln?
yes we made that kind of hypothesis but still looking for another explantation for this subject
This is the metallurgy terms and occurs diopside-fluorapatite based glass-ceramics from blast furnace slag and fluorite tailings the only crystallization product fluorapatite (Ca5(PO4)3F). With respect to thermal behavior of glass, heat treatment of glass with the composition of 40 wt% of blast furnace slag and 60 wt% of fluorite tailings resulted in well sintered glass-ceramics with diopside and fluorapatite as the main crystalline phases. Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone.
