Abstract
PURPOSE: To improve the measurement accuracy, and facilitate measurement and maintenance operations by using a gaseous mixture capable of reversibly the carbon activity in a carbon-containing liquid metal.
CONSTITUTION: A hermetically closed vessel 2 made of a metal membrane forming a gas filling closed space 3 arranged in liquid sodium 4 and a hanging bell 8a of a constant-pressure volume meter 8 arranged in a thermostatic tank 9 are communicated with each other by means of a stainless steel gas conduit pipe 7 the inner diameter of which is selected to be as small as possible. A vacuum pump 20, and carbon series gaseous mixture bomb 22 are connected to the gas conduit pipe 7. Then, the gas filling closed space 3, gas conduit pipe 7 and hanging bell 8a are filled with a gaseous mixture of a predetermined pressure such as a CO-CO2 gaseous mixture of a pressure slightly lower than the atmospheric pressure. As a result, the filled gaseous mixture reflects the carbon activity in the liquid sodium 4 and varies the volume of carbon thereby to detect and measure the carbon activity without using a gas chromatography.
