· Na1 As1 O3

Sodium arsenate (NaAsO₃) is an inorganic compound belonging to the arsenic oxide family, typically encountered as a crystalline solid with semiconducting behavior. This material is primarily of research and specialized industrial interest rather than mainstream engineering use, with historical applications in glass manufacturing, wood preservatives, and semiconductor research contexts. While arsenic compounds have niche roles in high-frequency electronics and photovoltaic research, sodium arsenate specifically sees limited adoption due to toxicity concerns and the availability of less hazardous alternatives for most applications.
