Some say ITC, others zircon, for coating the inside of
fiber kilns.
Questions:
Is the chemistry of ITC similar to zircon?
What form does Zircon come in? and from where?whom?
How are they different in effect?
I want to stabilize the fiber and protect from salts. I
am more concerned with stabilising than insulation.
What say you all?
Jude

Jude, I checked some patent office documents for some of these coatings and
here's some of the info I found:

------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
A coating for protecting constructions against fire and heat, comprises 10 to
80% by weight of aluminous and/or Portland cement and 5 to 20% by weight of
hydrated trisodium phosphate (Na(3) PO(4).12H(2) O). A small but effective
amount of a flux can be included, which can be calcium borate and/or
fluorspar, the amount being effective to assure superficial sintering of the
refractory particles at a temperature between 850 deg. and 900 deg. C. This
temperature range is selected because if sintering takes place below 850 deg.
C., the cracks which form in the coating are filled too soon by fusion of the
inorganic particles under the action of the flux; while if sintering takes
place above 900 deg. C., the coating becomes detached from the supporting
surface because the binder loses all of its adhesive power. The coating can
also include inorganic particles, e.g. alumina, sand, perlite and/or
vermiculite, and also organic particles.

Continuation of (including streamline cont.) Ser. No. 321,294, Nov. 13, 1981,
abandoned.
A resin-bonded sand core for high-pressure die casting methods having a first
refractory coating, such as of silica, with an inorganic binding agent of
colloidal silica and a clay such as kaolin, and a second or top coating of a
refractory material containing zircon and an organic binding agent, which
combination of these two different coatings enables the bonded sand core to
have high pressure and temperature resistance, good washout resistance,
freedom from surface penetration, and good shake-out properties.

Abstract
------------------------------------------------------------------------
A high emissivity refractory coating comprising a cured coating composition
comprised of a powder mixture containing 17 to 22% by weight of silicon
carbide, 6 to 11% by weight of graphite, 17 to 22% by weight of aluminum
oxide, 2 to 5% by weight of silicon nitride, 8 to 12% by weight of tricobalt
tetroxide, 18 to 22% by weight of cobalt aluminum oxide and 18 to 23% by
weight of ferrosilicon, and an aqueous solution of potassium silicate. The
high emissivity refractory coating is applied onto the surface of furnace
refractories or ceramic fibers. The coating does not peel from the surface of
the furnace wall and increases the energy efficiency of the furnace.

Abstract
------------------------------------------------------------------------
A composition for coating the refractory liners of ladles and troughs for
pouring and/or conveying molten metals comprising an aqueous dispersion
containing finely divided zirconia, a colloidal silica, finely divided mica,
finely divided zircon, finely divided bentonite and, optionally, an inert
coloring agent. The coating composition is capable of re-bonding fractured
liners and the resulting coating prolongs the effective life of the liner and
exhibits superior reflectivity, causing the molten metal to retain its heat
which facilitates better pouring.
