Q1: What are the primary applications of ZnWO4 powder?
A1: Its main uses focus on two areas: radiation detection scintillators and high-efficiency photocatalysis, leveraging its luminescent and catalytic properties.
Q2: How should the appropriate powder particle size be selected?
A2: This depends on the application. Preparing high-transparency scintillation crystals requires specific particle size control; photocatalytic reactions typically necessitate finer powders to increase the reaction surface area.
Q3: How should the product be stored?
A3: Store in a sealed, moisture-proof container in a dry, light-protected environment. Avoid contact with strong acids or alkalis to maintain chemical stability.
Q4: How does it compare to CdWO₄ scintillators?
A4: ZnWO4 is non-toxic, has slightly lower density but shorter afterglow, and offers stable light output. It is an important eco-friendly scintillator choice, particularly in detectors requiring rapid response.
