Hollow polymer particles, method for preparing hollow polymer particles, porous ceramic filter, and method for preparing porous ceramic filter

摘要

Hollow polymer particles are provided to have an average particle diameter of 15 mum or more and 500 mum or less and a 10%-compressive strength of 1.5 MPa or more, and the hollow polymer particle includes a hollow portion in the interior. In addition, a porous ceramic filter is provided by firing a shaped material composed of a mixture in which the above-described hollow polymer particles are mixed to disperse in a ceramic composition.
