Use in ceramic mixes of aluminum-containing waste containing more than 50% Al
facilitates formation of
and mullite, which improves object physicomechanical and chemical properties. Use of alumi
num-containing waste containing less than 30% Al
does not facilitate formation of a-Al
mullite formation. Cristobalite does not form with use of aluminum-containing waste with an increased
amount of alkali (R
O > 11%), and this has an unfavorable effect on ceramic composite material

This research is a continuation of work  in which the
fundamental possibility was demonstrated of using alumi-
num-containing waste in the production of ceramic materials
for different purposes. In  raw material chemical, mineral
ogical, and production properties were studied, and composi
tions for ceramic mixes and physicochemical properties for
various purposes were given, although phase transformation
during ceramic material firing was not studied.
In the manufacture of ceramic building materials ques
tions concerning phase composition, sintering, and
physicochemical processes during object firing are of special
importance, since they govern the main operating properties
of objects . Physicochemical processes of structure forma
tion within composite ceramic materials using technogenic
raw material differ markedly from similar processes occur
ring within traditional natural raw materials used. These dif
ferences are due to superimposition of additional effects on
those known, in view of which they complicate the study of
new materials and require more detailed examination of the
technogenic raw material used.
The aim of this work is to study the phase composition of
ceramic materials based on aluminum-containing techno-
genic raw material without using traditional natural materi-
als. Introduction into the composition of ceramic mixes of
aluminum-containing waste due to an increased Al
tent within them makes it possible to improve acid resis
tance, thermal shock resistance, and frost resistance of ce
ramic composite materials considerably . In this work in
order to prepare composite ceramic material the argillaceous
component used was the clay part of zircon-ilmenite ore
gravitation tailings [3, 4], and the aluminum-containing
shortening material was slag from metallurgical production
of chromium, slag from melting carbon-free ferrochrome
[1, 5], slag from melting ferrotitanium [1, 6], slurry from alu
minum pickling production [1, 7], aluminum-containing
slurry obtained during cleaning of effluent from ethyl and
isopropyl benzene production [1, 8], nickel skeleton catalyst
slurry [1, 9], exhausted catalyst IM-2201 [1, 10, 11],
alumochromium waste from picking aluminum alloys, and
fired saline aluminum slags . The chemical compositions
of wastes are given in Table 1. Metallographic analysis was
performed in a MIN-8M microscope at a magnification of
200 in order to evaluate waste particle size. The average par
ticle size was 0.1–5ìm(Fig. 1).
