Sự khác biệt
| Mullit | Cordierite | |
| Thành phần | The main component is island aluminum silicate, the mineral composition is mainly sillimanite, and it also contains a small amount of quartz, biotite, phlogopite, chlorite, vân vân. | The main chemical components are magnesium aluminum silicate, in which the magnesium element can be replaced by a small amount of manganese, and the aluminum element can be replaced by high-valent iron. |
| Thành phần | Most of them are formed by the metamorphism of mudstone, and are generally formed under the conditions of high pressure of intermediate metamorphism. | It is a typical metamorphic mineral, mainly found in gneiss or schist with high aluminum content and altered igneous rocks, and also exists in magnesium-rich altered volcanic rocks. |
| Light | The surface is glassy and some have a cat’s eye effect. | When observed under sunlight, it has starlight effect, cat’s eye effect, gold dust effect, vân vân., and also has some fluorescent characteristics. |

- Metamorphic Minerals: Both are metamorphic minerals, formed under specific geological conditions.
- Applications: In some applications, such as ceramics and refractories, mullite Và cordierite may be mixed to improve the properties of the material.
