[Object] There is provided a porous sintered body has a uniform porosity, a high level of freedom in body formation which allows formation into varieties shapes and various levels of porosity, and a very large surface area. [Solution] The porous sintered body includes: hollow cores which follow a vanished shape of an interlaced or otherwise structured fibriform vanisher material; sintered walls 226 which extend longitudinally of the cores and obtained by sintering a first sintering powder held around the cores; and voids formed between the sintered walls. The cores and the voids communicate with each other via absent regions formed in the sintered walls. The sintered walls have surfaces formed with a sintered microparticulate layer 232 made from a material containing a second sintering powder which has a smaller diameter than the first sintering powder, and has predetermined pores 231.

A method of expanding expandable polymeric microspheres including contacting an aqueous slurry including unexpanded, expandable polymeric microspheres with heat in-situ during manufacture of a construction material. A method of manufacturing a construction material includes: (i) contacting an aqueous slurry of unexpanded, expandable polymeric microspheres with heat proximate to and/or during said manufacturing of the construction material to create expanded polymeric microspheres; (ii) optionally pre-wetting the expanded polymeric microspheres; and (iii) mixing the expanded polymeric microspheres with the construction material.

A thermally-insulating composite material with co-shrinkage in the form of an insulating material formed by the inclusion of microballoons in a matrix material such that the microballoons and the matrix material exhibit co-shrinkage upon processing. The thermally-insulating composite material can be formed by a variety of microballoon-matrix material combinations such as polymer microballoons in a preceramic matrix material. The matrix materials generally contain fine rigid fillers.

Provided herein are methods for making a freeze-cast material having a internal structure, the methods comprising steps of: determining the internal structure of the material, the internal structure having a plurality of pores, wherein: each of the plurality of pores has directionality; and the step of determining comprises: selecting a temperature gradient and a freezing front velocity to obtain the determined internal structure based on the selected temperature gradient and the selected freezing front velocity; directionally freezing a liquid formulation to form a frozen solid, the step of directionally freezing comprising: controlling the temperature gradient and the freezing front velocity to match the selected temperature gradient and the selected freezing front velocity during directionally freezing; wherein the liquid formulation comprises at least one solvent and at least one dispersed species; and subliming the at least one solvent out of the frozen solid to form the material.

A method for producing a form-stable phase-change material includes freezing a slurry of solid and solvent to provide a frozen slurry, exposing the frozen slurry to conditions causing sublimation of the frozen solvent to remove solvent and provide a body having vacancies therein, sintering the body to provide a scaffold, and adding a molten phase-change material to the scaffold to provide the form-stable phase-change material. The same scaffold when ground acts as a phase-change nucleating aid.
