LABORATORY PROCUREMENT SUPPORT
For grade selection, particle-size confirmation, documentation support or custom specification review, contact our technical sales team.
Why is the melting point of CdTe (1041 °C) only slightly lower than its boiling point (1050 °C)?
This narrow liquid range is characteristic of cadmium telluride and indicates that it readily sublimes. This property makes the powder well-suited for thin-film deposition via physical vapor transport or sublimation techniques, which are common in photovoltaic and infrared-optics research.
What batch-specific documentation is available for this 99.999% CdTe powder?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation of purity, particle size, and handling precautions. The product description explicitly states that this documentation is available for the customer's verification.
How does the -325 mesh particle size specification affect the handling and processing of CdTe powder for research applications?
The -325 mesh specification ensures a maximum particle size of approximately 44 µm, which facilitates uniform mixing, compaction, and evaporation during deposition processes. This fine particle size is particularly advantageous for achieving homogeneous thin films in photovoltaic semiconductor and infrared-optics research, as stated in the product's intended application scope.
Atomfair CdTe powder with 99.999% purity and -325 mesh is suitable for semiconductor and photovoltaic research, offering consistent particle size and high chemical purity. The narrow melting-to-boiling range and water insolubility require careful thermal control and dry processing methods.
Positive
- High Purity (99.999%): Minimizes impurity-related defects in photovoltaic and semiconductor devices, ensuring reliable experimental results.
- Consistent Particle Size (-325 mesh): Provides uniform particle size distribution for reproducible thin-film deposition and consistent material behavior in photovoltaic and infrared-optics research.
Trade-offs
- Narrow Liquid-Phase Window: Melting point (1,041 °C) and boiling point (1,050 °C) are only 9 °C apart, limiting the temperature range for melt processing and requiring precise thermal control.
- Water Insolubility: The material is insoluble in water, restricting wet chemical processing routes and necessitating dry handling or solvent-based alternatives for solution-phase applications.
