SEEBECK COEFFICIENT AND ELECTRICAL CONDUCTIVITY MEASUREMENT SYSTEM FOR MEASURING SEEBECK COEFFICIENT AND ELECTRICAL CONDUCTIVITY AT HIGH TEMPERATURE

摘要

PURPOSE: A seebeck coefficient and electrical conductivity measurement system is provided to measure a current applied to a sub-heater at the high temperature by forming a sample holder with alumina and forming the sub-heater with a platinum wire. CONSTITUTION: A tube(4) is inserted into an inside of an electric furnace. A sample is inserted into an inside of the tube in order to measure a seebeck coefficient and electrical conductivity thereof. A vacuum cap(6,8) is installed at both ends of the tube in order to form vacuum and gas atmosphere. A sample holder(10) is installed in the inside of the vacuum cap. The sample is inserted into the sample holder. The sample holder is inserted into the inside of the tube.
