One of the approaches to enhance the zirconia-based ceramics stability is the development of composite materials much less subject to adverse effects of t→m transformation.
The stability parameters for these two types of materials are also virtually the same.
Inferior microstructural uniformity, non-uniform distribution of component phases, combined with higher ‘tetragonality factor’ values lead to mechanical instability in ZTAC materials.

Building materials effects of Al Content and Physical Properties on the Electromagnetic Interference Shielding of Sn Based Coating Thin Layers Fei-Shuo Hung1, Fei-Yi Hung2*, Che-Ming Chiang1, Truan-Sheng Lui2 1 Department of Architecture, National Cheng Kung University, Tainan, TAIWAN 701. 2 Department of Materials Science and Engineering, National Cheng Kung University, Tainan, TAIWAN 701. 1Email: n7895122@mail.ncku.edu.tw , 2Email:a10170214@gmail.com Keywords: electromagnetic interference (EMI), Sn-Al, coating, sputtering ABSTRACT: This study coats complex colloid mixed with Sn-xAl powders and polyethylene on glass to examine the shield effect on electromagnetic interference (EMI).
Therefore, how to use building materials to improve the electromagnetic environment is not only a very important issue, but also conforms with the objective of green architecture [7].
Problems such as wear, peeling, oxidation, hard-working and expensive cost have resulted in the applied capacity of building materials to decrease.

Nanotechnology is the study of science of materials at nanoscale which help in enhancing the performance of processes.
Nanoparticles are the nano-sized materials in the range of 1-100 nm.
According to the particles size, they are used for applications in many research areas, such as, pharmaceuticals, materials, energy, and environments.
This may be in terms of development of better materials, drilling fluids, chemical agents for EOR or for exploration and development of an oilfield.
