Twice‐Functionalized Montmorillonite Nanosheets for Polymer‐Derived MMT‐SiOC Nanocomposites: Phase Formation and Porosity

open access: yesSmall, Volume 21, Issue 19, May 12, 2025.
Novel MMT‐SiOC ceramic nanocomposites are prepared. At 900°C and 1200°C, growth and refinement of a crystalline α‐SiO2 phase on the MMT nanoflakes led to 2 to 5 nm pores upon etching. The size of the SiO2 domains appeared to be diffusion‐limited by turbostratic C phases in the SiOC matrix.

Matrix compositions and their impact on grain growth and strength of oxide ceramic composites

open access: yesJournal of the American Ceramic Society, Volume 107, Issue 12, Page 8442-8458, December 2024.
Abstract Oxide ceramic matrix composites (Ox‐CMCs) are composed of porous matrices reinforced by dense fibers to achieve high damage tolerance. It is generally assumed that their mechanical properties are fiber dominant. However, fiber strength can also be influenced by the surrounding matrix as it can affect fiber grain growth.

Use of Mullite Whiskers for Aluminium Matrix Composites

open access: yesMaterials Transactions, JIM, 1993
A process for the synthesis of mullite whiskers by firing a mixture of kaolinite, aluminium fluorite and graphite is obtained. The mullite whiskers have bar like form with average width ranging from 0.05 to 3 μm and aspect ratio of about 20. The reinforcement with mullite whiskers results in drastical improvement in wear resistance of aluminium alloy ...
