Microcapsules having a wall of inorganic substance and process for the preparation thereof |
摘要 |
A process for preparing microcapsules comprising a core of highly viscous liquid substance encapsuled with a wall of an aggregate of finely divided silica powder, which comprises adding the highly viscous liquid substance into a powder bed of the finely divided silica powder under stirring with a cutter. The microcapsules thus obtained have such a structure that the core of highly viscous liquid substance is coated with a wall of an aggregate of the finely divided silica powder and a gelatinized layer formed between the wall and the liquid core substance.
