Controlled precipitation of an inorganic compound in solution using a polymeric matrix
Résumé
Precipitation of strontium molybdate was performed from aqueous solutions of sodium molybdate and strontium chloride in presence of hydroxypropylmethylcellulose. Three experiments were conducted: without cellulose, with dissolved cellulose and with a tablet containing cellulose and strontium chloride powder. The first one results in agglomerates of bipyramidal crystals, the second one in smaller monosized bipyramidal crystals and the last one in a mixture of bipyramidal, spherical, ellipsoidal particles and their agglomerates. Explanations based on the effect of solution viscosity are proposed.
