Foreword
The Refractory Materials Series was initiated in the hope of filling some
serious voids in the literature available for high temperature scientists, and
this new publication, High Temperature Oxides, edited by Dr. Allen M.
Alper, will clearly perform this function. For thousands of years, men have
worked with oxides at high temperatures—ceramics, cements, bricks, tiles,
glazes, etc. were widely applied long before their basic chemistry and physics
were understood. The application of modern methods has led to hundreds
of new oxide materials and thousands of new applications as ultra-pure
compounds, variable stoichiometries, and a great variety of physical and
chemical properties have been measured and characterized on the basis of
current theories.
In this sequence of volumes on High Temperature Oxides, Dr. Alper has
drawn on his own experience in geochemistry, ceramics and glass technology
to define the broadest coverage of this most important group of Refractory
Materials yet available in the literature. His co-authors include experts from
a variety of laboratories—industrial, government and academic. This group
of outstanding scientists has made an extensive yet critical coverage of oxides
and systems of oxides with emphasis on fundamental properties as well as
the important new technological developments.
It is my hope that this publication, joined by the earlier volumes of this
series, and those yet to be printed, will make the series of books on
Refractory Materials an indispensable tool for the modern high temperature
scientist.

Preface
In the past five years, transition metal oxides have grown in technical and
economic importance. They are now being widely used in chemistry and in
electronic, refractory, and aerospace applications. The following are dis-
cussed: yttria, thoria, lanthanide and actinide oxides, titanates, zirconia,
zirconates, zircon, hafnia and tantalum and niobium oxides.
Thoria-doped yttria ceramics are now becoming important specialty
ceramics. In the past few years, these materials have been perfected into
high-temperature, transparent ceramics. Lanthanide and actinide oxides are
now being widely used in chemicals, phosphors, lasers, and ceramics; these
oxides are discussed in depth. Titanates and some zirconates are being widely
used in electronic applications. Zirconia and zirconia-containing compounds
are some of the most widely used refractories. Since zirconia-containing com-
pounds are very important in complex refractories, much work has been
done to gain a better understanding of them. This work is reviewed to show
the relationship of these Zr0 solid solutions and compounds to composition
2
and temperature. The cost of Hf0 is decreasing and, consequently, this
2
very refractory oxide is becoming increasingly important. Recent research
on tantalum and niobium oxide-containing compounds is also reviewed.
For information on the transitional metal oxides of Cr, Μη, Fe, Co, Ni,
see Part I, entitled Magnesia, Lime, and Chrome Refractories. Those oxides
were included in Part I because they are extremely important in the manu-
facture of steel.
Part III will discuss the properties and fabrication of the more stable
oxides such as MgO, A1 0 , and BeO, which are widely used in ceramics
2 3
and glasses.
Part IV will review the most recent research and advances that have been
made in refractory glasses and glass-ceramics. Compounds containing
A1 0 , such as mullite and spinel, are discussed, and research work on
2 3
tungsten and zinc oxides is brought up to date. There is also an in-depth
chapter on slip-casting ceramics.
The editor wishes to thank Prof. John L. Margrave of Rice University
and Mrs. Thyrza C. Hanson and Dr. John H. Munier of Corning Glass
Works. Thanks are also given to all the contributors who made this volume
possible. Corning Glass Works and Sylvania Electric Products Inc. are also
acknowledged for their support.
