In the 1960s, as a copper electrode materials are widely used, the utilization rate of about 90%, graphite, only about 10%; the 21st century, more and more users began to choose as a graphite electrode materials in Europe, more than 90% The graphite electrode materials. Copper, which had been dominant electrode materials, graphite electrodes and its advantages compared to almost disappear. What led to this dramatic change? Of course, is that a lot of advantages Graphite electrodes.

Graphite used in a wide range of industries, will be used in almost every industry. On the industrial use of the artificial graphite, which is special GRAPHITE. According to their shape the way there are several types.

Carbon and graphite materials based on carbon-based solid non-metallic materials, which are basically non-carbon graphite material composed of carbon, graphite and the material is essentially composed of carbon graphite material. For the sake of simplicity, sometimes the carbon and graphite materials collectively known as the carbon material (or carbon material).

1. Dense crystalline graphite
Dense crystalline graphite block, also known as graphite. Such graphite crystal clear crystals visible to the naked eye. Particles larger than 0.1 mm in diameter, surface area on the scope of the 0.1-1m2 / g (F-Sorb 2400 Miriam BET surface area method of testing), arranged in crystal chaotic, massive structure was dense. This: The graphite is characterized by high grade, generally for the carbon content of 60 to 65 percent, sometimes up to 80 ~ 98%, but the creamy and plasticity of graphite flake as well. Graphite surface area is a very important study, graphite surface area of the test data is only detected by BET using the results are real and reliable, there are a lot of domestic equipment can only do a direct comparison method of detection, are also being eliminated. At present, domestic and specific surface area test unified multi-point BET method, at home and abroad to develop specific surface area measured by the standard testing methods are based on BET-based, reference is made to our national standards (GB / T 19587-2004) - gas adsorption BET principle Determination of solid material surface area. Detection of specific surface area is relatively time-consuming work, as the absorption capacity of the sample, some of the test samples may need to spend a full day, if the test did not achieve a fully automated process, and that testers can not leave on time and to A high degree of concentration, observation instrument panel, the control knob, a little inattentive when the testing process will lead to the failure of this test would be a waste of a lot of staff time. Real fully automated intelligent surface area product testing, test equipment industry will be in line with international standards, similar international products are all fully automated and manual equipment abroad have been eliminated. Real fully automated intelligent surface area analyzer, the test will be repeated from the mechanical operation of liberating greatly reduced the intensity of their work, simple training to improve work efficiency. Real fully automated intelligent meter surface area, greatly reducing the human error led to the operation, improve the accuracy of the test. F-Sorb 2400 surface area than the real test is to achieve BET method of detection equipment (both direct contrast) and, more importantly, F-Sorb 2400 test surface area is so far the only fully automated intelligent than the surface area of detection Equipment, the test results with the international high consistency, stability is also very good at the same time to reduce human error and improve the accuracy of test results.

Graphite carbon element is the crystallization of minerals, and its crystal framework for the layered hexagonal structure. Each network layer between the distance of 3.40, the same network layer of carbon atoms in the pitch for 1.42A. A six-crystal system, complete with layered cleavage. Cleavage face key elements to focus on the weak molecular attractive, so Natural floatability of its very good.
