However, if the proportion of carbon and silicon is appropriate, it can be a semiconductor. This kind of semiconductor, such as green silicon carbide and germanium, is a special kind of semiconductor material. Even if the temperature is as high as one thousand degrees, it still has the properties of a semiconductor. In alumina bauxite sintered corundum, the adjustment range is relatively large, and various oxides can be easily added, which can be used to improve various properties.

In general, the main material of pure emery is csi, csi is an atomic crystal; atomic crystals are non-conductive. The material of fused zirconia corundum is the same as that of fused chromium corundum, and the ingredients are adjusted according to the needs of users. The crystallization may be precipitated by calcium plagioclase, and each calcium oxide molecule consumes only one molecule of alumina, that is, each mass of calcium oxide consumes only 1.818 parts of alumina, resulting in 4.96 parts of calcium plagioclase.

The stronger the stirring force in the molten pool, the higher the qualified steel output. Promoting the application of black silicon carbide breathable bricks on ladle furnaces and out-of-furnace processing ladles has also achieved good results. Reducing the amount of high-priced ferroalloys on these two devices is a factor in their effectiveness. In addition to technological innovation in the field of refractory production, it can not only save energy significantly, reduce CO2 emissions, but also realize new green processes, such as general photovoltaic elements or wind power generation.

Microhardness uses diamond with the tip less than 1mm as the indenter, and the hardness of the substance is evaluated by the indentation of the test object. Microhardness hardness values are expressed in Kg / mm2. Mechanical strength refers to the ability of a substance to resist the damage of an external force. Under the action of an external force, a material will generate a resistance of equal size and opposite direction. The internal force is called stress.

Rhenium is actually an indirect and stricter regulation of the content of iron oxide. Scientific research and production practice of corundum crystals show that calcium oxide and magnesium oxide have a great influence on the quality of pink aluminum oxide. Even a small amount of CaO will consume a large amount of Al2O3 and generate calcium hexaaluminate, so the national standard stipulates CaO ≤ 0.45%. A small amount of MgO will also have a larger effect. Although the impact of silicon oxide on corundum is small, it still has an impact.

The newly developed chemical hardening process will definitely have a significant impact on sintered corundum. Chemical hardening is to immerse the material in a chemical flux that may be converted into an oxide, and then sinter at the material's porcelain temperature. Fiber wheels and other products made of pure black corundum are mainly used for polishing of various workpieces, especially stainless steel. When making such products, it is necessary to consider that the black corundum is a flexible wear-resistant material.
