However, due to the highly covalent bond characteristics, it is difficult to sinter these materials to full density.
In LPS-SiC materials, typically 5-15 mass% of the Al2O3-Y2O3 additive system is commonly used [1-29,77-79,81,82].

Second, through the creation of specialized undergraduate research funds, students do their own project leader, taking the initiative to link science and technology instructors.
This gives a higher requirement of the reform and construction of the university library, library network system, international journals and reference room.
This present cross-campus of many disciplines, scientific research projects can share with each other, and also avoid phenomenon of duplicate investment and projects and material resources waste in the construction of various colleges, laboratories and research centers.
With Social progress and development of science and technology, education reform is urgently needed to develop creative talents.

Agricultural waste, also known as agro-waste, is being used to fabricate AMCs using ceramic materials such as Al2O3 or SiC, providing additional strength reinforcement for the hybrid composite.
Materials and Method 2.1 Material Selection This study used slabs of commercially wrought Al-Mg-Si alloy metal as the matrix.
Chemically pure alumina particles with an average particle size of 28 mm was obtained and used as reinforcing materials.
Conclusion The use of GPPA particles as reinforcement in the fabrication of a hybrid aluminium matrix composite depicts an economical use of agro-waste materials in enhancing the properties of AMCs, thus reducing the need for synthetic fillers.
