How does the -100 mesh particle size and 99.999% purity of CdSe powder affect its performance in infrared optical windows?
The -100 mesh particle size ensures uniform particle distribution for pressing or sintering into dense optical windows, while 99.999% purity minimizes infrared absorption due to impurities, maximizing transparency. The material has a refractive index of 2.5 and a melting point of 1240 °C, supporting its use in IR instrument window applications.
What makes Atomfair CdSe powder suitable for photoresist research as an n-type II-VI semiconductor?
As an n-type II-VI semiconductor, CdSe exhibits photoconductivity and can be used in photoresist formulations where its direct bandgap enables sensitivity to specific wavelengths. The powder form allows dispersion in solvents and polymer binders for thin film deposition. The product is specifically intended for photoresist research as stated in the application scope.
What furnace or processing temperatures are required for sintering CdSe powder given its melting point of 1240 °C?
With a melting point of 1240 °C, CdSe powder requires high-temperature sintering furnaces for consolidation into optical elements or substrates. The density of 5.81 g/cm³ informs packing and green body density calculations, and the -100 mesh particle size facilitates uniform compaction during pressing prior to sintering.
Atomfair CdSe powder (99.999% purity, -100 mesh) is an n-type II-VI semiconductor suitable for infrared optical windows and photoresist research, with a high refractive index and melting point but requiring careful handling per safety data sheet.
Positive
- High purity and fine mesh: 99.999% purity and -100 mesh ensure consistent optical properties and minimize scattering in IR applications.
- Semiconductor for IR and photoresist: n-type II-VI semiconductor with infrared transparency, suitable for optical windows and photoresist research.
Trade-offs
- Safety data sheet compliance required: Handling and disposal must follow SDS guidelines; COA and SDS are available upon request for batch-specific confirmation.
- Narrow application scope: Designed specifically for infrared optical-window, infrared-instrument, and photoresist research; not for general semiconductor use.
