Claim:
1. A method for producing hydrogen gas, heat and an oxide component using a water splitting process comprising: (a) providing a first chamber filled with a liquid melt, the liquid melt includes an under-saturated molten gallium; (b) inserting a solid material feedstock into the molten gallium wherein the solid material feedstock is submerged into the molten gallium so that the solid material feedstock dissolves in the molten gallium; (c) passing a solid material-saturated molten gallium to a second chamber via fluid communication; (d) introducing water via a water inlet to the second chamber containing the solid material-saturated molten gallium; (e) reacting the solid material-saturated molten gallium with the water at a water-liquid melt interface so as to split the water into the hydrogen gas, the oxide component and heat until the solid material therein is depleted; (f) passing water-oxide mixture to a centrifuge via an outlet tube externally mounted with a heat exchanger pipe wherein the water-oxide mixture is centrifuged to separate the oxide component, the water and the molten gallium while removing excess heat; (g) passing the oxide component to a furnace wherein the oxide component is dehydrated and heated to generate an ultra-high purity (UHP) alumina; and (h) repeating the steps (b) through (g) until the solid material feedstock submerged is converted into the ultra-high purity (UHP) alumina; wherein the solid material feedstock is aluminum feedstock, the oxide component is aluminum hydroxide and the molten gallium consists essentially of about 100% (hundred percent) by weight.
