Wahjoedi Mechanical Engineering Department, Universiti Teknologi Petronas, Bandar Seri Iskandar, 31750 Tronoh, Perak, Malaysia atahirengg4051@yahoo.com Keywords: Alumina-Silica Sand Nanoparticle Composites, Mechanical Properties, Microstructures, Sintering Abstract Ceramic-ceramic composites are used around the world in demanding thermal, structural and electrical insulating applications.
Introduction Engineering ceramics have high stiffness, excellent thermal stability and relatively low density, but their brittleness impedes their use as structural materials.
This ceramic material and its composites are important for high-temperature engineering applications as structural advanced materials.

Therefore, the international promotion of Chinese language to achieve six major changes: the more a single foreign language teaching in all directions of Chinese Language Council International; from the foreigners, "Please come in" Learning Chinese into "Please come in" and "going out" a combination ; from professional Chinese language instruction into a mass, popular type, application type Chinese teaching; the education system into a simple teaching system of internal and external services to the community and serve the state, government and civil, domestic and abroad to advance the cause; promotion model implementation of the scheme undertaken by the government into a government driven by the market;-face from the paper-based materials to promote the main changes to the multimedia network [2] [3].
