Are emery and silicon carbide the same abrasive?

Regarding corundum and silicon carbide, the connection between the two is really unclear. Some people think that the two are the same thing, and some think it is not. But looking up information on the Internet, the two seem to be different. It is indeed the same thing, so are emery and silicon carbide the same thing?

To be honest, I dare not say yes, and I dare not say no. Since emery itself is an ambiguous term, it was indeed silicon carbide at the beginning. At that time, a scientist in the United States accidentally discovered silicon carbide in the laboratory, but he didn't know what it was, and its hardness was only a little worse than that of diamond, so he thought it was a mixture of diamonds, and then named it emery. That is to say, the emery at this time only refers to silicon carbide, but it is also divided into categories, such as black silicon carbide and green silicon carbide. the

However, with the development of my country's industry, the use of silicon carbide in abrasives and refractory materials has gradually become more widespread. At this time, people are no longer limited to silicon carbide as emery, but expand it into a general term, except for silicon carbide. In itself, white corundum, brown corundum, garnet sand known as natural corundum, etc. are all classified as corundum series, which led to the current situation. the

So, whether emery is silicon carbide or not depends on how you understand it! After all, it’s right, it’s not right, isn’t it?
