Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L. Calcium chromate solubility is 170 g/L, and at 0 o C calcium hypo chlorate solubility is 218 g/L. Solubility of other calcium compounds lies between the levels of these examples, for

Metallic conductivity in infinite-layer strontium iron …

2014/3/11· In comparison, metallic SrFeO 2 /KTO prepared at 250 C shows lattice constants of a = 0.398 nm, c = 0.3483 nm, which are very close to those of bulk SrFeO 2 without appliion of pressure (0 GPa). Therefore, we can reasonably exclude the chemical pressure effect as the origin of the observed metallic conduction.
