"Decoding 'xhmster 44' - The Mysterious Cipher
2. Experimental Section
2.1 Synthesis
High‑purity elemental reagents (Xh = K (99.95 %), La (99.9 %), M = Ti (99.99 %), Se (99.999 %)) were weighed in the stoichiometric ratio K₀.₅La₀.₅Ti₂Se₄ (nominal composition of Xhmster‑44) inside an argon‑filled glovebox (< 0.1 ppm O₂, H₂O). The mixture was loaded into an alumina crucible, sealed under vacuum (10⁻⁵ mbar) in a quartz ampoule, and subjected to a two‑step melt‑growth: xhmster 44
Guide to action:
- Pre‑reaction: 800 °C for 12 h (to form a homogeneous melt).
- Crystal growth: Slow cooling from 800 °C to 500 °C at 2 °C h⁻¹, followed by furnace cooling to room temperature.
