Assessment of Powder Characterization Methods for Advanced Ceramics



Lin-Sien H. Lum


This report summarizes the results of an international round robin study on advanced ceramic powders. Thirty-four laboratories from Belgium, Germany, Japan, Sweden and the U.S. representing industrial, academic and government research organizations participated in this program. The activities were conducted under the auspices of the International Energy Agency (IEA). The objectives of the IEA Subtask 10 were to evaluate test methods for the characterization of selected properties of ceramic powders through an international round robin study and to determine the repeatability and reproducibility of the test methods. The results will be used to develop recommendations for drafting of national and international standard test methods. The properties that were measured during this project consisted of: 1) Characterization of powders suspended in water (particle dispersion); 2) Characterization of spray dried powders (flow rate, particle size distribution, and moisture and binder content); and 3) Green body characterization (bulk density and strength). Three powders were studied: silicon nitride, silicon carbide, and aluminum oxide.
