Understanding Sample Preparation for Ceramic Materials

Sample preparation in analytical chemistry refers to the ways in which materials are treated prior to their analysis. Proper preparation is critical, as the analytical results are worthless if not representative of the full process. The sample preparation path includes collecting samples from a running process or out of inventory, size reduction to a size suitable for the analytical tools, and
