Abstract
There is set forth herein a silicon-based patch formulation comprising about 25 to 66 percent by volume of a solvent; about 4 to 10 percent by volume of a silicon-comprising binding material; and about 30 to 65 percent by volume of a patching material, the patching material comprising particles having one or more non-actinide Group IIIA elements, wherein a molar ratio of the one or more non-actinide Group IIIA elements to silicon within the patch formulation is about 0.95 to 1.25.
Claims21
A silicon-based patch formulation comprising:
- about 25 to 66 percent by volume of a solvent;
- about 4 to 10 percent by volume of a silicon-comprising binding material;
- and
- about 30 to 65 percent by volume of a patching material, the patching material comprising particles having one or more non-actinide Group IIIA elements, wherein a molar ratio of the one or more non-actinide Group IIIA elements to silicon within the silicon-based patch formulation is about 0.95 to 1.25, wherein the particles having one or more non-actinide Group IIIA elements have at least a bimodal particle size distribution, wherein a particle size of a peak of a first distribution is greater than a particle size of a peak of a second distribution.
A silicon-based environmentally resistant patch comprising:
- about 2 to 10 percent by volume of a cured silicon-comprising binding material;
- about 90 to 98 percent by volume of a cured patching material wherein the cured patching material comprises particles having one or more non-actinide Group IIIA elements;
- and wherein a molar ratio of the one or more non-actinide Group IIIA elements to silicon within the silicon-based environmentally resistant patch is about 0.95 to 1.25, wherein the particles having one or more non-actinide Group IIIA elements comprise one or more rare earth materials selected from a group consisting of a rare earth (RE) monosilicate (RE2SiO5) and a rare earth disilicate (RE2Si2O7), and wherein the rare earth material is chosen from a group consisting of non-actinide Group IIIA elements.
