Combining three handbook results, sodium nitrate could be described as a colourless hygroscopic crystalline solid, as white granules or as a white powder, deliquesc in moist air.

Physical state at 20°C and 1013 hPa:

-The CRC Handbook of Chemistry and Physics (80th ed.) describes sodium nitrate as colourless hexagonal crystals, hygroscopic.

-The Merck Index (12th ed.) describes sodium nitrate as colourless transparent crystals, white granules or powder, deliquesc in moist air.

-Sax's Dangerous Properties of Industrial Materials (9th. ed.) describes sodium nitrate as colourless, transparent, trigonal (rhombohedral) crystals, deliquesc in moist air.
