Gallium phosphide powder is a high-purity III-V compound semiconductor material with the chemical formula GaP. This product typically appears as a fine crystalline powder ranging from yellow to orange-yellow in color, featuring an indirect bandgap width of approximately 2.26 eV. Renowned for its specific luminescent properties in the visible light spectrum, high electron mobility, and excellent chemical stability, it serves as a crucial base material for fabricating specialty functional materials, traditional optoelectronic devices, and conducting materials science research.
We offer high-quality gallium phosphide powder in multiple purity grades, particle size distributions, and doping types. Contact us.

Q1: What are the primary characteristics of GaP powder?
A1: Its core features are an indirect bandgap and visible light emission. Its yellow appearance and specific bandgap width distinguish it from materials like GaAs, which is primarily used for infrared light.
Q2: How should powder particle size be selected?
A2: This depends on the final process. Finer powders are required for preparing uniform composites or slurries; certain sintering or solid-phase reaction processes demand specific particle size distributions.
Q3: What precautions should be taken during use and storage?
A3: Store in sealed containers to prevent moisture absorption. Avoid inhaling dust during handling, and conduct operations in well-ventilated areas.
Q4: Is GaP still mainstream in optoelectronic devices?
A4: It has been replaced by materials like InGaN in ultra-high-brightness visible LEDs. However, it retains application value in specific wavelength devices, optoelectronic integration, and certain fundamental research.
