NOVELTY - Performing sample packaging method involves selecting metal crucible with a cover as sample container, selecting foamed metal or foamed graphene as heat conducting foam of sample heat conducting reinforced network, and weighing sample and sheet heat conducting foam. The heat conducting foam is added into metal crucible disc piece by piece if the sample powder is solid. The pores of heat conducting foam and gaps between heat conducting foam and inner wall surface of metal crucible disc are filled with sample powder after adding heat conducting foam piece each time, and sample powder and sheet heat conducting foam are compacted by using a mold. The two are stirred uniformly and added into a crucible tray if the sample is a liquid sample, corresponding metal crucible cover is covered, and the crucible is pressed and sealed. USE - Method for performing sample packaging method for measuring heat capacity of agglomerated substance used in field of metering and testing in physics, chemistry, material and communication fields. ADVANTAGE - The packaging method has the advantages of convenient operation, tight sample sealing, and significantly improve the thermal conductivity between samples and between the samples and container. The packaging method has strong versatility, is suitable for most solid and liquid samples, is suitable for heat capacity determination of relaxation calorimetry, differential scanning calorimetry and differential thermal analysis, and used as a standard package sample for heat capacity test method. The metal crucible, foamed metal and the foamed graphene used are all commercial consumables, and the price is moderate, which meets the requirements of wide popularization and application.
