Cynthia Bolon 213 Schrenk Hall [email protected] 341-4439 OBJECTIVES: Course objectives are to develop facility with performing laboratory techniques involving the handling of organic chemicals safely and the keeping of proper records of experiments conducted in the laboratory. Crystallization, distillation, extraction and chromatography are emphasized as separation and purification techniques. Melting points, boiling points, and refractive indices are used routinely as measures of purity. Safe handling of chemicals and proper disposal of waste products are priority goals in this course. To help in attaining such goals, the first week of the semester is devoted to SAFETY in the chemistry laboratory. For the remainder of the semester, most of the experiments are conducted on a micro scale.

Microstructural Measurements on Ceramics and Hardmetals
A NATIONAL MEASUREMENT A NATIONAL MEASUREMENT GOOD PRACTICE GUIDE GOOD PRACTICE GUIDE No. 21 No. 21 Microstructural Microstructural Measurements on Measurements on Ceramics and Ceramics and Hardmetals Hardmetals Measurement Good Practice Guide No. 21 Measurement Good Practice Guide No. 21 Microstructural Measurements on Ceramics and Hardmetals Eric Bennett, Lewis Lay, Roger Morrell, Bryan Roebuck Centre for Materials Measurement and Technology National Physical Laboratory Abstract: This guide is intended to review the importance of microstructure in determining the properties and performance of technical ceramics and hardmetals. It also promotes good practice in characterising those microstructural features which are relevant to materials performance in order that more informed choices of material can be made for specific applications. Microstructural parameters are described. They are typically characterised in several ways, including measures of grain size, crystallite texture, porosity, and phase volume fractions, as well as the detection of occasional features such as cracks, abnormal grains and inclusions. The importance of microstructural characterisation of these classes of material is reviewed, and possible measurement methods and methods of preparation of test-pieces for making the measurements are described. Based on information taken from the technical literature as well as data generated during NPL research programmes, correlations between microstructural parameters and properties are discussed.

A Method for Digital Image Analysis of Ceramic Grains Based on Shape Factor Segmentation
A METHOD FOR DIGITAL IMAGE ANALYSIS OF CERAMIC GRAINS BASED ON SHAPE FACTOR SEGMENTATION Elson de Campos (1); Émerson F. de Lucena (1); Francisco C.L. de Melo (2); Luis Rogerio de O. Hein (1) 1Laboratório de Análise de Imagens de Materiais (LAIMat), Departamento de Materiais e Tecnologia (DMT), Faculdade de Engenharia do Campus de Guaratinguetá (FEG), Universidade Estadual Paulista (UNESP), 12516-410, Guaratinguetá, SP, Brazil, [email protected] 2 Divisão de Materiais (AMR), Instituto de Aeronáutica e Espaço (IAE), Centro Técnico Aeroespacial (CTA), São José dos Campos, SP, Brazil ABSTRACT A very simple and robust method for ceramics grains quantitative image analysis is presented. Based on the use of optimal imaging conditions for reflective light microscopy of bulk samples, a digital image processing routine was developed for shading correction, noise suppressing and contours enhancement. Image analysis was done for grains selected according to their concavities, evaluated by the perimeter ratio shape factor, to avoid consider the effects of breakouts and ghost boundaries due to ceramographic preparation limitations. As an example, the method was applied for two ceramics, to compare grain size and morphology distributions. In this case, most of artifacts introduced by ceramographic preparation could be discarded due to the use of the perimeter ratio exclusion range. Keywords: digital image analysis, perimeter ratio, ceramography, reflective light microscopy 1.Introduction: Ceramics have been used in many engineering applications, which have resulted in extensive research. Most morphological characterization of ceramic grains are performed by qualitative microstructural observations by scanning electron microscope (SEM) [1-5] or few quantitative information [6,7]. -
