This research aims to study and develop ceramics material using in the wall construction which can be used to proof the heat and water reduce absorbed humidity in the building. The product can save the energy especially the building which is set the air conditioning. The experiment found that the proportion of clay body can be developed and the result of thermal conductivity (K- value) was 0.111 W/ m. /K the permeability was 7 percent the glaze can be used to proof water. The product was compared to three kinds of construction materials which are brick concrete masonry unit and autoclaved aerated concrete found that K- value and permeability were lower. Moreover it can proof water and save more energy for the air conditioning building.

In this study we investigated the effects of Sm2O3 addition in ceramics 0.93(Bi0.5- x/0 . 9 3Smx/0 . 9 3Na0 . 5 ) TiO3 - 0 . 0 7 BaTiO3 by mixing solid oxide solutions. The crystalline properties of the X-ray diffraction and ferroelectric properties were studied from the P - E loop. The physical properties showed that BSNT-BT ceramic density increased and the percentage of shrinkage decreased due to the increase of the amount of Sm2O3. Moreover it was found that the results were consistent with the structural study for sintered samples at a temperature of 950 °C for 7 hours. It can be determined that the BSNT-BT ceramics have a perovskite structure which is like the main structure of ceramic type BNT. Dielectric properties and dielectric losses at room temperature showed that when increasing the amount of Sm2O3 in BSNT-BT ceramics the dielectric and low dielectric loss were consistent with reduced material resistance. Further the ferroelectric test found that BSNT-BT ceramics improved the ferroelectric properties when increasing the amount of Sm2O3 in the BSNT-BT ceramics.
