How to judge the life and hardness of silicon carbide
The price of black silicon carbide is still judged in many aspects, and now there are many performances of black silicon carbide in these aspects, and it is constantly improving in all aspects. After perfecting, the overall effect is better, and with the present The development between the industries is getting better and better. The overall materials are also constantly increasing. After the increase, the number of workmen is also more, and with the development of the industry is getting faster and faster, in all aspects The competitiveness of the black silicon carbide industry is still relatively large, and it is precisely because of these competitiveness that the black silicon carbide industry is constantly advancing constantly, and in many ways, in the next few decades, it is actually black. Silicon carbide still occupies a certain position.
With the continuous development of technology, the development between the industries is getting faster and faster. Now all walks of life are constantly developing, and because of the development of the industry, in the past few years, the economy has been The better, and the people's living standards are getting higher and higher, but the environmental problems are outstanding, and in recent years, the number of trees is decreasing every year, and the number of trees is decreasing. It affects water resources and air quality, because trees are supposed to absorb carbon dioxide, release oxygen, and protect the woods.
Black silicon carbide is black, and its microscopic shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.2, the microhardness is 3000--3300 kg/mm 2 , the hardness is 2670-2815 kg/mm, and the microhardness is 3300 kg per Cubic millimeters. The density is generally considered to be 3.20 g/mm 3 , and the natural bulk density of the silicon carbide abrasive is between 1.2 and 1.6 g/mm 3 and the specific gravity is 3.20 to 3.25. The number of sand grains is 12.14.16.20.22.24.26.30.36.46.60.80.90.100.120.150.180.240.280. It is mainly used for hardness alloys, titanium alloys, stainless steel, copper, aluminum, zinc, ceramics, stone, agate, Grinding and polishing of jade, fine jewelry, electronic components and other materials. Not only can you make abrasive tools and advanced refractory materials. It can also be used in other industries.
