WebDec 1, 2024 · In this study, β-tricalcium phosphate/montmorillonite biocomposites were prepared by sintering powder at 900 °C of apatitic tricalcium phosphate in the presence of Na-montmorillonite. The addition of the clay with concentration from 2 to 10 wt.% did not affect the final β-TCP phase. WebMost phosphate rock is used to produce soluble P fertilizers, but some is used for direct application to soil. While phosphate rock can be a valuable source of P for plants, it’s not always appropriate for direct application. Its suitability depends partly on naturally occurring mineral impurities, such as clay, carbonate, iron and aluminum.
