What is the difference between natural corundum (garnet) and artificial corundum (brown corundum)?
Natural carborundum is garnet sand, which is a natural abrasive and is directly mined from mines. The raw materials are made into abrasive materials by screening and grading methods, without manual smelting. The processing time is short, the efficiency is high, and the price is low, which can make up for the short lifespan. insufficient. It is widely used in sandblasting and rust removal, water jet cutting, filter media, grinding, wear-resistant floors, etc., and has roughly the same function as artificial emery. In appearance, it is similar to artificial emery or brown corundum.
The differences are summarized in the following points:
1. Since natural emery has not been artificially smelted, its service life is shorter than that of artificial emery, but the price is also lower than that of artificial emery.
2. The chemical composition of natural emery is more complex than that of artificial emery, mainly containing SiO2, Al2O3, Fe2O3, TiO2, MgO, FeO, CaO, MnO, etc. The main component of artificial emery is Al2O3, and the content is higher.
3. The hardness of natural emery is slightly lower than that of artificial emery, its Mohs hardness is 7.5~7.9, and the artificial emery is above 9.0.
Fourth, the origin is different. Natural emery origins are represented by Inner Mongolia, Lianyungang and Rizhao, and artificial emery can be produced in places with abundant bauxite resources.
5. Artificial emery abrasives are more widely used than natural emery abrasives, especially in refractory materials, ceramics and other industries other than sandblasting and polishing.
