This proceeding includes original and peer-reviewed research papers from the 3rd International Conference on Frontiers of Materials Synthesis and Processing (FMSP 2019), which held from 9 to 10 November 2019, in Sanya City, China. FMSP 2019 aims at creating a meeting point for researchers and practitioners that from both China and abroad to exchange ideas in the domain of Materials Synthesis and Processing and related topics with its prospective application in the various interdisciplinary domains of engineering, including not only technological issues but also social issues. FMSP 2019 received 791 manuscripts, and 120 submissions had been accepted by our reviewers. Articles submitted to the conference should report original, previously unpublished research results, experimental or theoretical and must not be under consideration for publication elsewhere. We firmly believe that ethical conduct is the most essential virtual of any academic. Hence any act of plagiarism is a totally unacceptable academic misconduct and cannot be tolerated. The committees of FMSP 2019 invested great efforts in reviewing the papers submitted to the conference and organizing the sessions to enable the participants to gain maximum benefit. Hopefully, all participants and other interested readers will benefit scientifically from the proceedings and also find it stimulating in the process. With our warmest regards, Lin Liu Conference Organizing Chair Wuhan, China
