Abstract
A core-shell particle is provided, including a core particle composed of a non-reactive component, and a coating layer disposed about the core particle, the coating layer composed of reactive component. The reactive component is chemically reactive with water, acid, or base, and the non-reactive component is non-reactive with water, acid, or base. Also provided are a bulk composition composed of the core-shell particle, an article composed of the bulk composition, as well as method and system of making and using the particles, composition, and articles.
Claims19
A bulk composition having a multiphase morphology, the bulk composition comprising:
- a dissolvable continuous phase of a matrix material comprising a reactive component that is chemically reactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- and
- a non-dissolvable discontinuous phase including a plurality of particles of a non-reactive component that are chemically unreactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- wherein the plurality of particles are distributed within the matrix material;
- wherein the reactive component and the non-reactive component are not galvanically reactive with each other;
- wherein the matrix material is from 1 to 25 wt. % of the bulk composition, based on a total weight of the bulk composition;
- and
- wherein the reactive component comprises graphite, K, Na, V, Li, W, Mo, Al4C3, AlP, Ba, BaH2, BaSe, BaSi2, BP, CaC3, CaH2, Ca2P2, CaSi2, CaC2, Mg2Si, SiS, or ZrCl3.
An article of manufacture comprising:
- a bulk composition having a multiphase morphology, the bulk composition including a continuous phase of a matrix material comprising a reactive component that is chemically reactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- and a discontinuous phase including a plurality of particles of a non-reactive component that are chemically unreactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- wherein the plurality of particles are distributed within the matrix material;
- wherein the reactive component and the non-reactive component are not galvanically reactive with each other, wherein the matrix material is from 1 to 25 wt. % of the bulk composition, based on a total weight of the bulk composition, and wherein the reactive component comprises graphite, K, Na, V, Li, W, Mo, Al4C3, AlP, Ba, BaH2, BaSe, BaSi2, BP, CaC3, CaH2, Ca2P2, CaSi2, CaC2, Mg2Si, SiS, or ZrCl3.
