This research aims to study and test a ceramic product in using to constructs a wall. This research is based on a previous studying to develop a ceramic product that saves the energy in the building. The early test shows the product has out door heat resisting capability and it is very user-friendly. However the test was only an early stage. The research still lack of a real life situation test and has very little feedback from the consumers. All of which are very importance to farther develop this product into a production stage. The research has 2 steps. First step to testing the heat and humidity resisting quality of the product the researcher is building four testing blocks (dimension 1x1x1 meter). Each block has different material on one of its side block 1 has brick block 2 has concrete masonry unit block 3 has autoclaved aerated concrete and block 4 has ceramic block. The other three side of each block have a heated and humidity resisting form. The researches test the following; heat energy the temperature inside the blocks and humidity inside the block. After comparing the difference between the airs inside and out-side of the blocks the block 2 with concrete masonry unit has the best humidity resisting quality and is the most user-friendly product. In the term of heat resisting block 3 with autoclaved aerated concrete perform the best. Second step to test the user-friendliness of the product the researcher found 2 groups of consumers. First group are the wall constructing expert. This group has a hard time using this product and can’t get use d to the product so they find this product to be too thin and too weak. Second group the home owner feel the product has a thinner wall and believe it’s weaker than a typical construction brick. There for they still don’t know how to use this product.

การเตรียมและการวิเคราะห์แก้วและแก้วเซรามิกชีวภาพจากระบบแคลเซียมโซเดียมฟอสเฟต
การเตรียมและการวิเคราะห์แก้วและแก้วเซรามิกชีวภาพจากระบบแคลเซียมโซเดียมฟอสเฟต

The aim of this work was to study the magnetic properties of magnetic glassceramics with composition system CaO-Na2O-P2O5-BaO-Fe2O3. The magnetic glass– ceramics were prepared by conventional melting at 1300oC for 2 h of the coprecipitation derived starting products and heat treated at different temperatures. The structure and microstructure of the samples were characterized by X-ray diffraction energy dispersive X-ray analysis (EDXA) and scanning electron microscopy. The magnetic measurement showed that the samples which contained barium ferrite exhibited magnetic behavior which is similar to soft magnetic materials. Finally the samples were soaked in simulated body fluid (SBF) for 14 days. The apatite was found to form on the surface layer of glass-ceramics and it increases with the barium ferrite content was increased.

Design and Product Development Ceramics Using for Making Wall of Energy Conservation Building
Design and Product Development Ceramics Using for Making Wall of Energy Conservation Building

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.
