The present invention discloses a solid-solid direct-heating reaction disc arrangement comprising a reaction disc body, clampers, a heater and a driving plate. Holding slots for receiving reaction cups are formed axially through the reaction disc body at constant intervals. The dampers are mounted to the bottom surface of the reaction disc body and each comprise an upper damper and a lower damper which are fastened together. The bottom surfaces of the reaction cups rest on the upper clamper. The heater is sandwiched between the upper and lower dampers for heating the reaction disc body and the reaction cups. The driving plate is mounted to a supporting plate of the reaction disc body. By arranging the reaction disc body, the clampers, the heater and the driving plate in a receiving chamber defined by a cover and an insulation casing, a closed temperature control system is formed.
