| 摘要 |
<p>A composition produced by a hydrothermal liquid phase sintering process, which process comprises allowing at least one component of a porous matrix to undergo a reaction with at least a first reactant carried by a liquid to provide at least a first product, during which reaction a remainder of the porous matrix acts as a scaffold for facilitating the formation of the at least first product from the liquid, thereby producing a hydrothermal liquid phase sintered composition, wherein the porous matrix comprises a metal oxide, metal hydroxide, metal sulfate, metal titanate, or a combination thereof, wherein the first product comprises carbonate, sulfate, oxalate, fluorophosphate, calcium, magnesium, strontium, titanium, zirconium, chromium, manganese, iron, nickel, copper, aluminium, or a mixture thereof, and wherein the hydrothermal liquid phase sintered composition substantially maintains the predetermined shape and size of the porous matrix, and wherein the first reactant comprises oxalate, carbonate, sulfate, fluorophosphates, metal ion, or a combination thereof.</p> |
