Disclosed is a container for the thermal analysis of cast iron that enables a reduction in the amount of tellurium used in thermal analysis. By forming a plurality of fine spaces in the interior of a base plate (12) and sidewalls (11), thermal insulating properties are maintained in the base plate (12) and the sidewalls (11) and the temperature of a sample of the cast iron melt placed in the interior of the container (1) is prevented from cooling down. As a result, even if the amount of a sample supplied for thermal analysis is reduced, the speed by which the temperature of the sample drops is suppressed, and a constant temperature is maintained by the heat from the latent heat of solidification. Accordingly, the amount of tellurium used in thermal analysis can be reduced by reducing the amount of the sample supplied for thermal analysis.
A method of thermal analysis of cast iron by measuring a primary crystallization temperature and an eutectic temperature by solidifying molten cast iron in a state containing tellurium and determining the contents of carbon and silicon contained in the cast iron based on the measured primary crystallization temperature and eutectic temperature,
