Topotactic growth of α-alumina platelets on 2/1 mullite single crystal surfaces upon thermal decomposition of mullite in dry and wet atmospheres

The crystalline-to-amorphous transition in shock-loaded mullite Al2VI(Al2+2xSi2−2x)IVO10−x in the light of shear modulus anisotropy

“…Numerous phase boundaries filled with amorphous silica become visible in the transformed region upon defocusing the objective lens. Considering the original mullite orientation prior to thermal decomposition, similar [0 1 0]//[1 0 · 0] and [1 0 0]//[0 0 · 1]-type mullite/corundum orientation relationships as described elsewhere 39 were locally established in shocked mullite crystal.…”

Single and polycrystalline mullite fibres grown by laser floating zone technique

“…The same technique was used to grow the MSCs characterized in several works published by the group led by Prof. Schneider. 1,2,[6][7][8][9][10][11] The ICM method allows the production of very thin MSCs with about 0.1 mm in diameter and high aspect-ratio (ap. 800), which are more adequate for mechanical reinforcement uses.…”
