Journal of Materials Research and Technology, 2023 Fabrication and filtering performance of ceramic filter were investigated to reduce non-exhaust particulate matter (PM) from vehicles. For this purpose, filter needs to be porous structure with high mechanical strength, thus it can be operated with low ...

Structure and composition characterization of submicronic mullite whiskers [PDF]
Journal of Materials Research, 1991 Two sets of submicronic mullite whiskers, which have potential applications for fiber reinforced composites or as a thermal insulator, have been characterized to be tetragonal or orthorhombic using x-ray and electron microscopy techniques. The whiskers decompose upon heating under vacuum with a continuous loss of silicon and reduction in oxygen content

Toughening effect of mullite whisker within low-density ceramic proppants
Advanced Composites Letters, 2019 Main crystal phases of low-density ceramic proppants prepared by bauxite and feldspar are granular corundum and whisker-shaped mullite. Mullite whiskers are interlocked with one another and piled up inside the pores. High aspect ratio of mullite whiskers

Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers [PDF]
, 2018 Chemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer and they remain for 28 days ...
