**5. Conclusions**

In this study, we discussed how it affects already atomized bronze sulfide. Specifically, the strength of bronze matrix and the reaction between sulfide and hydrogen gas are drawing attention. We will clarify the composition and atmosphere effective for sintering bronze with sulfide dispersed. As a result, copper sulfide can sinter several types of atmosphere such as inert, reducing, and vacuum. In many reducing conditions, attention is paid to the disappearance of sulfides from
