The major constituents, CaO and P2Os, accounted for 86–89% of the ashed granules. The granules also contained Na, K, Mg (as oxides) and Cl which added up to 10–14 %. Although the X-ray diffraction patterns indicated only poorly formed apatite; the infrared spectrum could be interpreted as arising from poorly crystallized apatite and/or a partially dehydrated or hydrolysed octacalcium phosphate either or both mixed with anhydrous dicalcium phosphate. The formation of pyrophosphate (44·5 %) in the ignited granules indicated the presence of considerable acid phosphate in the original material.", }
