The creation of new porous permeable ceramic materials with a different microstructure and a controlled pore
size from nano- to microsize that have properties markedly surpassing those of traditional materials used in in
dustry, and organization of the production of various objects made from them will make it possible to obtain a
considerable economic and ecological effect. Specific examples are provided for the use of objects made of
porous permeable ceramics developed in ZAO NTTs Bakor in various branches of industry.
The problem of doubling the internal gross product is
closely connected with resolving problems of the ecology
and economics of natural non-renewable energy resources.
One of the main ways for resolving the problem may be, and
should become, creation of new materials, organization of
the production of various objects made from them and exten-
sive use of these objects in various branches of industry in-
stead of objects made from morally aging traditionally used
Over fifteen years the scientific and technical center
Bakor has been occupied in developing and producing spe
cial forms of advanced ceramic and refractory materials. One
of the priority areas in this activity is creation and production
of porous permeable ceramic materials with pores controlled
from nano-to microsizes for the manufacture of filtering ele
ments used in filtration units of various types . As the
practice of using objects made of porous permeable materials
has shown, this material in the present stage of development
of the technology manifests itself in the most important
branches of industry for the national economy.
Filtering elements made from porous permeable ceram
ics in ZAO NTTs Bakor of find extensive use in the mining
and metallurgical industry for filtering solutions of electro
lytes and dewatering flotation concentrates before
More than ten years ago in the mining and metallurgical
industry commenced extensive use for candle-shaped filter
ing units intended for filtering solutions of the electrolytes of
copper, nickel, cobalt, in which on a industrial scale filtering
elements made from porous permeable ceramic (Fig. 1) were
used for the first time.
Before this, filtering presses of the open type were used
in order to filter electrolyte solutions. The consumption of
filtering cloth (belting) reached 120 thousand m
the wood for making frames and plates reached 1800 m
the practice of using candle-shaped filtering units has shown,
they are simple for servicing and they their specific produc
tivity is greater by a factor of ten than for filter presses of the
open type (Table 1).
