Claims20
An inorganic shell, being hollow, and being sintered with inorganic powder, the inorganic powder comprising silica and crystalline inorganics.
A resin composition, comprising:
- resin material;
- and
- inorganic shells, the inorganic shells being dispersed in the resin material, each inorganic shell being hollow and comprising silica and crystalline inorganic powder sintered together with the silica by a high temperature sintering process.
A method for making an inorganic shell, comprising:
- providing a mold, the mold being made of material that can be volatilized at a certainly temperature;
- providing inorganic powder comprising silica and crystalline inorganic powder;
- adsorbing the inorganic powder on surface of the mold;
- sintering the mold and the inorganic powder, and then, volatilizing the mold to obtain an inorganic shell.
