Cordierite-based ceramics with coffee husk ash addition: I –microstructure and physical properties

open access: yesJournal of Materials Research and Technology, 2021
Cordierite is one of the compounds in the MgO–Al2O3–SiO2 system which has the lowest thermal expansion coefficient. Despite this advantage, which results in high resistance to thermal shock, monophasic cordierite is difficult to prepare due to its narrow

Effect of particle size on the pore characterization and strength of porous cordierite-mullite ceramics prepared by a pore-forming in-situ technique [PDF]

open access: yesScience of Sintering, 2013
The porous cordierite-mullite ceramics were prepared by the pore-forming in-situ technique. The characterizations of porous cordierite-mullite ceramics were determined by an X-ray diffractometer (XRD), a scanning electron microscopy (SEM), and a ...

Evaluacion termica, mecanica y electrica de materiales compuestos cordierita-mullita

open access: yesMaterials Research, 2000
Commercially available cordierite and mullite powders were used to obtain cordierite and cordierite-30wt% mullite materials by attrition milling, uniaxial pressing and sintering. Cordierite powders were the coarse (D50 = 1.82 mum), medium (D50 = 0.9 mum)
