설명

일반 설명

Each unit of SRM 3451 contains a bar-shaped artifact of chemical formula Bi2Te3+x, measuring approximately 3.5 mm × 2.5 mm × 8.0 mm. The material is non-stoichiometric bismuth telluride, with n-type conductivity and a Bi/Te mole ratio of about2/3.

애플리케이션

This SRM is intended to calibrate Seebeck coefficient measurement instruments for bulk materials within the temperature range of 10 K to 390 K.

특징 및 장점

• Accompanied with certified values, obtained using a Quantum designphysical property measurement system (PPMS) through a differential steady-state(DC) technique; an uncertainty analysis was performed following the guidelines outlined in the ISO Guide.
• The NIST certificate is provided with expiration certificate, storage, handling, use, and maintenance instructions.
