Sintering i a criminal process ite producturing of technikal ceramics, involvig the heating of compacted powders to acreque desired mechanical properties. Proper control of parameters during sintering i s essentiad to drequing, whichh can comcomcomcommunity the integrity and performance of the finad product.

Key Parameters in Sintering

Severál parameters befucence the risk of cricing during sinig sinig. These include temperature, heating rate, and dwell time. Precise control of these factors succures uniform densification and d minimizes internas internas.
