Cold Sintering of Calcium Carbonate for Construction
Sintering of ZnO using acetic acid solution is shown to reduce the porosity and BET surface area. This improvement is more pronounced compared to sintering of calcium carbonate samples showing higher efficiency of acetic acid solution in sintering of ZnO (Figure 8) than NaOH solution in sintering of calcium carbonate (Figures 6 and 7).

Calcium Carbonate Side Effects Dosages Treatment
Calcium Carbonate is a medication used to prevent or treat low blood calcium levels in people who do not get enough calcium from their diets. It may be used to treat conditions caused by low calcium levels such as bone loss (osteoporosis) weak bones (osteomalacia/rickets) decreased activity of the parathyroid gland (hypoparathyroidism) and a certain muscle disease (latent tetany).
