Patent RU 2383514
The invention pertains to a composition of protective
coatings and may be used in the chemical, metallurgical, and
aviation industries, for example, in the production of carbon
materials and articles made of carbon materials. The techni-
cal result of the invention lies in the improvement of the ad-
hesive characteristics and in an increase in the thermal stabil-
ity of a coating. A protective coating, containing potassium
water glass and a powder-like filler is distinguished by the
fact that it contains silicon carbide, graphite, and sodium
fluosilicate as the powder-like filler at the following ratios,
wt.%: potassium silicate water glass, 100 – 150, silicon car-
bide 100 – 200, graphite 1 – 12, and sodium fluosilicate
0 – 12.

Patent RU 2384545
IPC C04B33/22, C04B33/16
The invention pertains to the fabrication of refractory
brick for the drip-pan of a float bath, i.e., a bath with tin used
in the fabrication of sheet glass. The technical result of the
invention lies in moderation of the reaction with Na
the glass to the surface of the refractory brick for the purpose
of prevention of flaking.
1. A method of fabricating refractory brick for the
drip-pan of a float bath comprising addition of a potassium
compound to a clay substance containing 30 – 45 wt.%
and 50 – 65 wt.% SiO
; moderation; molding; roast
ing; crushing of the material to obtain granulated refractory
material; mixing of the granulated refractory material; mold
ing into a refractory brick for the drip-pan of a float bath of
required form with subsequent roasting at which the content
O in the fine granulated fraction (<90 mm) is regulated
to ensure it amounts to 2 – 4% while the content of Na
not more than 1%.
2. A method of fabricating refractory brick in accor
dance with Part 1 in which the granulated refractory material
contains 20 – 60 wt.% fine granulated fraction (90 mm) with
O and not more than 1% Na
3. A method of fabricating refractory brick in accor-
dance with Part 1 in which the content of K
O in the interme-
diate granulated fraction (from 90 mm to 1 mm) and in the
fine granulated fraction (90 mm) is regulated to ensure that it
amounts to 2 – 4% and to ensure that the content of Na
not greater than 1%.
4. A method of fabricating refractory brick in accor-
dance with Part 3 in which the granulated refractory material
contains 20 – 60 wt.% granulated intermediate fraction (from
90 mm to 1 mm).
5. Refractory brick containing 30 – 45 wt.% Al
50 – 65 wt.% SiO
and no more than 1% Na
O and 3 – 4%
6. Refractory brick in accordance with Part 5 containing
at most 10% crystalline phase of cristoballite.
7. Refractory brick in accordance with Part 5 containing
at least 20% crystalline fraction of mullite.
8. A float bath with drip-pan produced from brick de
scribed in Parts5–7.
9. A method of producing sheet glass that includes the
use of a float bath in accordance with Part 8.
