SnS2 Tin Sulfide Crystal 99.995%, ~8mm Box ATOMFAIR®

What is the typical crystal phase and morphology of 99.995% SnS2 supplied as ~8mm orange-yellow pieces?

This product is a layered crystal material with a purity of 99.995%, supplied as ~8mm orange-yellow pieces in a box. The source specifies the color and size but does not explicitly state the crystal phase (e.g., 2H or 4H polytype) or detailed morphology beyond 'layered crystal material'; for phase confirmation, contact the manufacturer.

Can this SnS2 crystal be directly used in exfoliation for 2D device fabrication without additional purification?

Yes, the 99.995% purity and ~8mm size are suitable for mechanical exfoliation into thin flakes for 2D device research. The high purity minimizes contamination, and the ~8mm crystal provides sufficient area for exfoliation, but the source does not specify surface quality or defect density, so pre-characterization is recommended.

What storage and handling conditions are required for SnS2 crystals to prevent degradation?

The product is packaged in a box, but the source does not specify inert atmosphere or desiccant requirements. SnS2 is generally air-stable under ambient conditions, but to maintain the 99.995% purity and orange-yellow color, store in a dry, dark environment away from moisture and strong oxidizers. For long-term storage, consider a desiccator or argon-filled glovebox.
