Mullite-2c – a natural polytype of mullite
, 2020 A single crystal (∼ 20 µm × 20 µm × 330 µm) of mullite-2c, a natural polytype of mullite, was separated from a radially grown cluster of acicular crystals from Ettringer Bellerberg (Quarternary Eifel volcanic fields, Germany).

Light-Absorbing-Layer-Free Flash Lamp Annealing for High-Throughput Fabrication of All-Solution-Processed Oxide Electronics. [PDF]
Adv Sci (Weinh)A flash lamp annealing strategy using a mullite chuck enables rapid conversion of sol–gels to metal oxides on silicon and ultra‐thin glass without extra light‐absorbing layers. Direct light absorption initiates the transformation, and the low thermal conductivity of mullite promotes heat accumulation.

Cobalt incorporation in mullite [PDF]
Acta Crystallographica Section A Foundations of Crystallography, 2005 Mullite (nominally 3Al_2O_3.2SiO_2) is technologically important material for advanced ceramics applications. Depending on the synthesis procedure, mullite is able to incorporate considerable amounts of transition metal cations [1]. While Cr^3+, Fe^3+ and V^3+ have the strongest tendency of incorporation in mulllite, only low or very low amounts of Fe ...
