in Ceramics: William H. McCracken
Bill
McCracken has left his imprint on refractory raw materials
in the world of ceramics. Some of his many international
projects and developments in the world of refractories
include: a 50,000 annual tonnage magnesite mining/rotary
kiln project in northeastern Brazil; raw material exploration
and development of natural resources in Peru; and evaluating
refractory raw materials and their potential in more than
40 other countries of the world. Kathy L. Woodard
Precollege
Education Program Comes Full Circle ACerS student member Jennifer Sigman was one of many
high school students who knew the career path she wanted
to pursue prior to graduation. With a keen interest in
science and her father's electrical engineering influences,
Sigman wanted to be an engineer. Choosing which area of
engineering to study began when Sigman's advanced physics
class went on a field trip to the ACerS headquarters to
learn about ceramics through a "Ceramic Science & Technology
Days" tour. Kathy Martin
Dispersion of Microsilica-Containing Zero-Cement High-Alumina Castables Based on the zeta potential data obtained, citric
acid can be an effective dispersant for microsilica-containing
zero-content high-alumina castables. A.R. Studart, W. Zhong, R.G. Pileggi,
P. Bonadia and V.C. Pandolfelli
Developing a Taphole Mass Using Statistical DOX Statistical design of experiment method was used to
develop a tailor-made taphole mass for use in a blast
furnace. Simulative testing equipment assessed its viability
in actual working conditions. D. Halder, N.K. Ghosh, P.K. Roychowdhury,
A.K. Bhattacharya and D.P. Chakraborti
Microstructural Characteristics of Refractory Composites SEM, TEM and HREM have been used to study microstructural
characteristics of oxide-nonoxide composites; commonly
found microcracks led to improved thermal shock resistance. X. Zhong and H. Zhao
Ideas Flow at Fine, Ultrafine and Nano Powders '99 A brief overview of some of the new technological
developments and market opportunities discussed in the
workshop and conference sessions at Fine, Ultrafine and
Nano Powders '99. Mindy N. Rittner
The Search for New Red Pigments Limited pigment choices for porcelain stoneware tile
led to a search for new pigments or new synthetic routes
for the use of old ones in efforts to obtain different
shades of red and orange. F. Bondioli and T. Manfredini
One-Dimensional Packing of Spheres, Part I A new type of particle packing model that packs 3-D
particles along a one-dimensional line is neither limited
by the large memory requirements nor the long running
times that severely restrict the use of 3-D models. Part
I of this two-part series addresses monodisperse and bimodal
distributions. Dennis R. Dinger
