- Cordierite
(mineralogy) or iolite (gemology) is a magnesium iron aluminium
cyclosilicate.
- Cordierite typically
occurs in contact or regional metamorphism of argillaceous
rocks.
- Two common
metamorphic mineral assemblages include sillimanite-cordierite-spinel
and cordierite-spinel-plagioclase-orthopyroxene.
- Cordierite most
important feature is that it has a very low coefficient of thermal
expansion and excellent resistance to thermal shock.
- Cordierite was known
and used as a gemstone in Sri Lanka.
- Cordierite materials
and others based on it are magnesium aluminosilicates, fabricated by
sintering soapstone or talcum with the addition of clay, kaolin,
fireclay, corundum and mullite.
- Cordierite can be
made in high volume through cost-effective extrusion or dry-pressing
methods.
- Cordierite is a
common constituent in contact metamorphosed argillaceous or arenaceous
sediments and in regionally metamorphosed settings where it occurs only
in high grade gneiss
- The
dumortierite-bearing cordierite-orthoamphibole rocks occur as thin
layers and lenses in the upper-amphibolite facies area of the central
part of the Bamble Sector
- Cordierite diesel
particulate filters provide an economical approach to diesel emissions
control.
- Cordierite honeycomb
monoliths of square channels were used as substrates for the
Preparation of Washcoated Monolith.
- Indialite, the rare
high-temperature hexagonal form of cordierite. Synthetic hexagonal
cordierite is often found in glass ceramics and has a wide range of
technical applications
- Synthetized
cordierite was used as a refractory filler in the ceramic layer for
evaporative polystyrene patterns in the new casting technology, Lost
Foam Process.
- The spectroscopic
micro-FTIR technique has been used to examine a series of natural
cordierite samples of different geological environments and chemical
composition.
- The channel H2O,
CO2, and alkali contents of 33 natural cordierites have been analyzed
using a combination of Fourier-transform infrared spectroscopy (FrrR),
electron-microprobe analysis, and chemical and isotopic
techniques.
- Kiln furniture
usually is made of cordierite or various types of silicon carbide.
High-value silicon carbide kiln furniture is a growing market, whereas
the market for cordierite is shrinking.
- The official
concedes that the biggest drawback of silicon-carbide is cost: estimated
at 15-20 percent more than cordierite.
- Cordierites have low
coefficients of thermal expansion and excellent resistance to thermal
shock. They offer a range of thermal expansion, mechanical strength and
porosity criteria. They excel as cost-effective extruded and dry-pressed
forms.
- 447 offers excellent
thermal shock resistance with high continuous porosity, suitable for
applications such as welding tile.
- 547 offers very good
thermal shock resistance with improved flexural strength due to its
semivitreous properties. It is able to withstand rapid temperature
fluctuations, such as those found in oil burner applications.
- 701 also offers very
good thermal shock resistance, good flexural strength and 0-1% porosity
due to its vitrified properties. This cordierite can self-glaze. It is
suitable for applications such as commercial heater supports.
