An analysis is made of the many years of experience in designing and improving industrial technologies
which use quartz-glass HCBSs (highly concentrated ceramic binding suspensions) and high-alumina compos
ite HCBSs to make shaped and unshaped refractories that are effective products for customers and sources of
profit for manufacturers. Long before the current boom in nanomaterials, HCBS-based technologies em-
ployed elements that are part of nanotechnologies now in widespread use and are responsible for the high
technical-economic efficiency of these materials. The volume of commercial production (CP) of the
refractories at the OAO “Dinur” jumped 55% from 2013 to 2014. CP volume in the first quarter of 2015 in-
creased by factors of 2.7 and 2.0 compared to the same periods in 2013 and 2014. Over three decades of use of
the above technologies, Dinur has produced roughly 180,000 tons of highly profitable refractories that in cur-
rent prices are worth about 12 billion rubles.

In the 2007 publication , devoted to the 75th anniver
sary of the Open JSC “Dinur,” it was noted that through no
fault of its own the company lost its near-monopoly on its
main product — dinas — during the 1990s when the intro
duction of market reforms caused its dinas output to fall
5 – 6-fold. The drop in dinas production accelerated during
subsequent years early in the Twenty-First Century, and the
company’s current output of dinas is less than 10% of the
level reached in the 1980s. Such a precipitous decline in vol
ume of orders for firm’s dinas products have led to a situa
tion in which a single tunnel furnace is now used for this pur
pose and the duration of the firing operation has doubled
(due to the light work load). Given this and the low volume
of orders, dinas production has obviously become unprofit
able at the plant.
In light of these circumstances, the company realized
that in order to survive it had to extricate itself from this situ
ation. The challenge it faced was to develop and successfully
introduce new technologies that allow it to manufacture prof
itable products in large volumes. To a significant extent,
Dinur has managed to achieve these goals through the devel
opment and mass production of various types of shaped and
unshaped refractories made on the basis of highly concen
trated ceramic binding suspensions (HCBSs) [1 – 15].
ORIGINS OF THE NEW TECHNOLOGIES
AND THE DIRECTIONS IN WHICH THEY
ARE BEING DIVERSIFIED

logical aspects of the research and development work that
led to the creation and practical success of the new branch of
