Dispersion and Rheology Control for Improved Ceramic Processing
Sunday May 3, 2020 1:00 p.m. – 5:00 p.m., and Monday May 4, 2020, 8:30 a.m. – 4:00 p.m.
Marriott Cleveland Airport, Cleveland, Ohio
Instructor: William M. Carty, Alfred University
This course is intended for those who need a better understanding of the variables that control suspension properties, knowledge of the analytical tools needed to decipher defect causes, and the background to have a reasonable place to start when trouble-shooting manufacturing problems associated with raw material variations, rheology excursions, and processing problems.
The course will introduce the five factors that control suspension rheology with examples. The five factors include:
- Powder characterization and the role of powder properties (i.e., density, surface area, and particle size distribution) with hands-on examples.
- Stabilization mechanisms (electrostatic, electrosteric, and steric stabilization) investigated to provide background for evaluating behavior and trouble-shooting.
- Aqueous processing and ionic strength
- Ceramic forming techniques from a perspective that ties all slurry forming techniques together (extrusion, injection molding, tape casting, and slip casting)
- Defect generation
Participants are encouraged to bring example defects or problems to the course for general discussion. Students will be provided a printed “laboratory manual” with descriptive text, experiments, data, homework problems and worked examples. Copies of the presentation and other reference materials will also be provided.
William M. Carty, Ph.D., joined the faculty at Alfred University in 1993 and achieved the rank of Professor in 2002, McMahon Professor in 2010, and Chair of Ceramic Engineering and Glass Engineering Science (2008 and 2010). He received a B.S. (1985) and M.S. (1987) both in Ceramic Engineering from the University of Missouri-Rolla, and a Ph.D. in Materials Science from the University of Washington (Seattle, 1992).
Carty joined Alfred University following a one-year post-doctoral position at Koninklijke/Shell-Laboratorium, Amsterdam (The Netherlands). He has worked closely with industry during his tenure at Alfred University and has generated over $18 million in research funding, mostly with industrial projects or by leveraging industrial funds with New York State funding sources. His current research interests are ceramic processing and microstructural evolution (in both traditional and advanced ceramic materials); tailoring microstructures and porosity for specific applications; the connection between strength and processing; glass batch reactions and melting; and the development of sustainable ceramic manufacturing processes (i.e., energy efficient and environmentally-sound). In addition to teaching and research, he is a world-recognized expert and consultant in porcelains and glazes, ceramic processing, and ceramic manufacturing
