NOVELTY - Heat sinterability of metal particles coated in organic material is evaluated by subjecting both metal particles and organic material to thermal analysis in an air current and comparing the thermal decomposition peak temperature (1) of the organic material coating the surface of metal particles and thermal decomposition peak temperature (2) of organic material. The activation energy of organic material is calculated from relationship between temperature increase rate and the temperature (1), and the heat sinterability of the metal particles is evaluated based on the calculated value.    USE - Method for evaluating heat sinterability of metal particles-coated organic material for manufacturing heat sinterable metal paste used for manufacturing metal component bonded product (all claimed). Uses include but are not limited to resistor, capacitor, diode, memory, electrode of solar cell, laminated ceramic capacitor, laminated ceramic inductor, laminated ceramic actuator, central processing unit, etc.    ADVANTAGE - The heat-sinterable metal paste formed using the organic material-coated metal particles provides metal component bonded product with excellent bondability, thermal conductivity and electroconductivity. The bonded product is easily and efficiently manufactured.    DETAILED DESCRIPTION - Heat sinterability of metal particles coated in organic material is evaluated by subjecting both metal particles and organic material to thermal analysis in an air current and comparing the thermal decomposition peak temperature (1) of the organic material coating the surface of the metal particles and the thermal decomposition peak temperature (2) of the organic material. The heat sinterability of coated metal particles is high when temperatures (1,2) are same. The activation energy of the organic material in the thermal decomposition reaction is calculated from the relationship between the rate of temperature increase during thermal analysis and the thermal decomposition peak temperature (1) of the organic material coating the surface of the metal particles, and the heat sinterability of the metal particles is evaluated based on the calculated value. INDEPENDENT CLAIMS are included for the following:    (1) method for producing heat sinterable metal paste; and    (2) manufacture of metal component bonded product.
