Research about the ceramic. These are some example of research that SIRIM may consider them. 1 . Electroceramics Electroceramics represent a multi-billion pound industry worldwide providing important components for consumer electronics, mobile communications, control systems and sensors for automobiles and aeroplanes, and protection devices for a wide range of power and electronic systems. Control of the microstructure at scales from the grain to the grain boundary to individual point defects is vitally important if he electroceramics are to yield optimum performance. 2.
Ceramic Coatings The research aim is to develop these ceramic coatings with enhanced performance at high temperature. The thermal barrier coating research concentrates on novel fabrication of TBCs, non-destructive evaluation of TBCs, and a degradation study of TBCs after thermal treatments. The research on fuel particles involves chemical vapour deposition of Pyc and SIC layers on fuel particles, and characterisation of coated particles using various modern advanced techniques. The Sic coating esearch is to study strengthening mechanisms of the SIC with the addition of carbon or diamond. . Advanced Characterisation Techniques There are a large number of macroscopic physical properties associated with the different ceramic forms that are used for making microwave dielectrics, heat resistant coatings, superconductors, transformer cores and thermistors. In many cases subtle variations in the atomic structure of these materials leads to significant changes in physical properties. In order to study these atomic structural changes and o correlate them with the physical macroscopic properties.
Advanced characterisation tools: Synchrotron X-ray powder diffraction – X-ray powder diffraction is one of the most commonly used tools in the study of crystalline phases; residual stresses and quantitative analysis. The use of synchrotron X-rays can extend the range and complexity of the materials under study. The data can be used in conjunction with other measurement such as resistivity or temperature in order to directly correlate a atomic structural change with the macroscopic properties.
Energy dispersive X-ray diffraction – We use this method to scan over a fabricated ceramic component to build up a 3D density contrast map (like a tomograph) that also contains structural and chemical information. This technique (called TEDDI) is being developed in the Manchester Materials Science Centre and gives a valuable (and non destructive) insight into ceramic manufacture. Small crystal crystallography – If ceramic grains are separable from the bulk they can be studied using synchrotron X-ray small molecule crystallography.
Currently the record for a structure solved in this way is from a grain with an average dimension of 4 micron. The advantage if this method is that it gives unambiguous information about the atomic arrangement in the material but the disadvantage is that it may not be representative of the bulk. Time resolved crystallography – A new detector called RAPID2 (Refined ADC Per Input Detector version 2) is still a world leader in the field of rapid, high resolution powder diffraction. The new station at the SRS can collect data at millisec rates or better and ith no loss in peak resolution.
We have a capability that can deliver fast high resolution (refinable) diffraction data from operational materials. This is opening up completely new insights into the way functional materials respond to their imposed environment. Conclusion First of all, we need thanks to DR CNA and Mr Khairil because they brought us to visit SIRM company at Shah Alam. We have gained new knowledge from our visit to SIRIM. It was an interesting and valuable visit which taught us a lot about ceramic. A eramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material.
The special character of ceramic materials gives rise to many applications in materials engineering, electrical engineering, chemical engineering and mechanical engineering. There are two type of ceramic, crystalline ceramics and noncrystalline ceramics.
