Abstract
Magnesium phosphate (Mg3(PO4)2) is an organic compound formed from magnesium salts derived from phosphoric acid (H3PO4) in other words, elemental magnesium that is sandwiched between the phosphate anions. In addition, magnesium phosphate has been needed by industry, especially in the field of advanced and biological materials. However, what is currently needed is the high price of basic materials that require imports. The mineral dolomite is widely distributed in Indonesia, contains calcium (Ca) and magnesium (Mg) in it so that it can be used as an alternative base material for the synthesis of magnesium phosphate. The steps in the manufacture of magnesium phosphate are calcination, dissolution of dolomite minerals with phosphoric acid using the extraction aeration method, and the last process is crystallization. The research variables used variations in the concentration of phosphoric acid (H3PO4), namely 8N and 10N, and airflow rates of 1, 2, and 3 L/min. The results presented regarding the characteristics of magnesium phosphate obtained using the XRF method (X-Ray Fluorensence) and SEM EDX (Scanning Electron Microscope – Energy Dispersive X-Ray). From these results, it can be used as a reference for the characteristics of magnesium phosphate obtained from the synthesis of dolomite minerals.
