Sep 22, 2020The model for the thermal decomposition of calcium carbonate was proposed to be R 2 [ 22] which can be expressed as: (1) where is the model of R 2, α is the conversion percentage. Although there are several functional mechanisms to describe the decomposition reaction of solids, they are obtained on the basis of a single influencing factor [ 23 ].

Rationale: The AI for 0-6 months was set by multiplying together the average intake of breast milk (0.78 L/day) and the average concentration of calcium in breast milk (264 mg/L) from 10 studies reviewed by Atkinson et al (1995), and rounding. Formula-fed babies require additional intakes in the vicinity of 350 mg/day as calcium is less bioavailable in formula.
