Do corundum brick and corundum not come why does Shi Zhuanru differentiate?

Corundum brick and corundum not come stone brick is two kinds of different fireproof material, they are being comprised and differ somewhat on property, because this is OK,undertake differentiating through a few methods.
Chemical composition: Corundum brick is main by alumina (Al2O3) composition, and Mo Laishi brick includes corundum corundum (Al2O3) with Molaishi (Mullite) two kinds of composition. The chemical part that you can tell material of beyond the mark analyse will distinguish they.
Color: Normally the circumstance falls, corundum brick is white or flaxen, and Mo Laishi brick may show corundum gray or brown. The difference of color also can help you undertake the abecedarian distinguishs.
Content reason is simple: The brick is in corundum brick and corundum Mo Laishi the likelihood on physical property has a few to differ, wait like density, hardness. You can use physical property test to distinguish they, for example hardness checks or density checks.


Microstructure: Use microscope or photomicrography equipment observe the micromechanism of material. Mo Laishi brick has corundum normally structure of clear Mo Laishi crystal, and the structure of corundum brick is close to single corundum crystal more.
X ray diffraction analyses: This is a kind of reliable analysis technology, can use the crystal structure of certain material. Through undertaking X ray diffraction is analysed, the composition of well and truly certain material and crystal structure, distinguish thereby corundum brick and corundum Mo Laishi brick.
Anyhow, the brick can pass corundum brick and corundum Mo Laishi a variety of methods such as property of chemical composition, color, physics, microstructure and analytic technology will undertake distinguishing. If need is accurate,differentiate these two kinds of material, the likelihood needs to undertake the lab is analysed or use professional device.
