Cordierite is a kind of aluminum magnesium silicate mineral, generally blue, because of its dichroism, it is also called dichroic stone. https://www.rtoceramic.com/products/
1, Cordierite name
Cordierite is also known as dichroic stone, and some people call it “water blue stone”.
2. Cordierite composition
The molecular formula of natural cordierite is 2MgO·2Al2O3·5SiO2, and the theoretical composition is MgO 13.5%, Al2O334.9%, SiO2 51.3%. In fact, the chemical composition of cordierite is often different from the theoretical composition. And the cordierite is called iron cordierite when the iron content is higher, and the manganese content is called manganese cordierite.
3, cordierite properties
There are three crystal types of cordierite:
(1) α-cordierite, hexagonal symmetrical structure;
(2) β-cordierite, rhombic crystal system;
(3) μ-cordierite, rhomboid crystal phase.
Color is generally blue, light blue, gray blue, smoke blue, dark blue and other blue, from a certain direction. They often like the wood violet flower of the dark blue (violet), and from this direct direction, it is gray or yellow, because of this dichroism, it is also called dichroic stone, cordierite crystal is more than a short column, with glass luster, density: 2.60g/cm3; Mohs hardness 7~7.5; Transparent ~ translucent. Cordierite has the characteristics of low thermal expansion coefficient, small thermal conductivity, good thermal shock resistance, low dielectric constant, small dielectric loss and good chemical stability.https://www.chempackings.com/honeycomb-ceramic/catalyst-carrier-cordierite-honeycomb.html
