In one aspect, a lithium manganese iron phosphate material includes a core, and a material of the core is represented by a general formula of Li.sub.xMg.sub.yMn.sub.zFe.sub.aAl.sub.bPO.sub.4, where x is ranged from 1.008 to 1.05, y is ranged from 0 to 0.006, z is ranged from 0.4 to 0.6, a is ranged from 0.388 to 0.6, and b is ranged from 0 to 0.012.

The present disclosure is generally directed to methods for forming anhydrous rare earth and actinide phosphate minerals. In some embodiments of the present disclosure, the method generally comprises subjecting rare earth or actinide phosphates or salts thereof to microwave radiation.

The present disclosure is directed to a method of manufacture of zeolite. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include zeolite with increased crystallinity relative to comparable sol-gel formulations without ODSO as a precursor. In additional embodiments, the rate of crystallization of the zeolite is greater relative to comparable sol-gel formulations without ODSO.

In one aspect, a sheet shaped ferric phosphate with a high iron-to-phosphorus ratio has a sheet shaped structure with an iron-to-phosphorus (Fe/P) ratio greater than 0.99, a ratio of length to width to thickness of the sheet shaped structure is (105 to 130):(90 to 100):(10 to 12), 3.5 m.sup.2/ga specific surface area of the sheet shaped structure6.5 m.sup.2/g, and a particle size of the sheet shaped structure<35 m.
