    When lime separates from the decomposition of carbonato‐apatites, the phosphate recrystallises to fluor‐apatite and sinters. Ferric oxide progressively increases lime sintering at 800°, 900°, 1000° and 1100°. Like anhydrite, its low Tammann temperature (650°) readily permits ion diffusion into lime cracks and fissures, promoting sintering.
