Tin Selenide Powder Description
Tin Selenide Powder, or SnSe Powder, is a gray orthorhombic crystal with semiconductor properties. It is insoluble in water, but soluble in nitric acid and aqua regia. Tin selenide exhibits low thermal conductivity as well as reasonable electrical conductivity, creating the possibility of it being used in thermoelectric materials. Stanford Advanced Materials (SAM) has over two decades’ experience in the manufacture and sale of Tin Selenide Powder.

Tin Selenide Powder Applications
Thermoelectric Devices – Used in energy harvesting and cooling systems due to its high thermoelectric efficiency and low thermal conductivity.
Photovoltaic Cells – Employed in solar energy conversion as a light-absorbing material for thin-film solar cells.
Optoelectronics – Applied in infrared detectors, sensors, and other optoelectronic devices because of its tunable bandgap and semiconductor properties.

FAQs
How is SnSe Powder synthesized?
Common methods include solid-state reaction, chemical vapor transport (CVT), ball milling, and solution-based synthesis (e.g., solvothermal).
Is SnSe Powder toxic or hazardous?
Yes, selenium compounds can be toxic if inhaled or ingested. Proper handling (gloves, masks, fume hoods) and storage are required.
How does SnSe compare to other thermoelectric materials?
SnSe has a higher thermoelectric figure of merit (ZT) than traditional materials like Bi₂Te₃ but is less commercially mature.
