摘要： The present disclosure, in various embodiments, discloses hydrothermal methods, hydrothermally modified materials and dried hydrothermally modified materials. Certain dried hydrothermally modified materials can readily releases ionic species such as alkali metal ions (K+, Na+), silicate salts, and alkaline earth metal ions (Mg2+, Ca2+). Some dried hydrothermally modified materials can readily release aluminum ions and/or silicon, such as in the form of soluble silicates. Such processes and materials are useful, for example in economically preparing potassium releasing fertilizers.

摘要： A method, comprising: heating at a temperature of at least 90° C. for a time of at least 10 minutes and a pressure of at least one atmosphere: 1) a potassic framework silicate ore; 2) at least one material selected from the group consisting of an oxide, a hydroxide, and a carbonate of at least one of an alkaline earth metal and an alkali metal; and 3) water, thereby producing a first product; combining the first product with a source of a component to form a second product; and drying the second product to provide a composition comprising an MPM and the component, wherein the source of the component comprises at least one member selected from the group consisting of KCl, a macronutrient source, a micronutrient source and a source of a beneficial element. A composition, comprising: an MPM; and a component selected from the group consisting of a KCl, a macronutrient, a micronutrient and a beneficial element, wherein the MPM comprises at least two phases selected from the group consisting of K-feldspar phase, tobermorite phase, hydrogrossular phase, dicalcium silicate hydrate phase and amorphous phase.

摘要： Multi-step methods of making an MPM include at least first and second steps. The first step can be performed at relatively low temperature and/or a relatively low pressure. The second step can be performed at a relatively high temperature and/or a relatively high pressure. The first step can be performed in one or more reaction vessels. and the second step can be performed in one or more different reaction vessels.
