How to broaden the application scope of silicon metal powder?
Although, after a period of development, more and more people know and understand the silicon metal powder, but the understanding is not comprehensive. Our company has been providing silicon metal powder for a long time. After long-term contact, we have a very good understanding of all aspects of silicon metal powder. In order to return the majority of users for many years of support, but also in order to further broaden the scope of application of silicon metal powder, our company will be for the performance of silicon metal powder simple explanation.
1, high temperature resistance, silicon metal melting point of 3850±50℃, boiling point of 4250℃, even by ultra high temperature arc burning, weight loss is very small, the coefficient of thermal expansion is very small. The strength of silicon metal is strengthened with the increase of temperature. At 2000℃, the strength of silicon metal is doubled.
2, electrical conductivity, thermal conductivity, silicon metal conductivity is one hundred times higher than the general non-metallic ore. The thermal conductivity is higher than steel, iron, lead and other metal materials. The coefficient of thermal conductivity decreases with the increase of temperature, even in the case of high temperature, silicon metal into an adiabatic body. Silicon metal conducts electricity because each carbon atom in silicon metal forms only three covalent bonds with other carbon atoms, and each carbon atom retains one free electron to transfer charge.
3. Lubricity, lubrication performance of silicon metal depends on the size of silicon metal scales, the larger the scale, the smaller the friction coefficient, the better the lubrication performance.
4, chemical stability, silicon metal has good chemical stability at room temperature, acid resistance, alkali resistance and organic solvent corrosion resistance.
5, plasticity, silicon metal toughness is good, can be ground into very thin sheets.
6, thermal shock resistance, silicon metal at room temperature when used to withstand drastic changes in temperature without damage, temperature sudden change, silicon metal volume change is not big, will not produce cracks.
The above is the introduction of the performance characteristics of silicon metal. I hope that we can deepen our understanding of silicon metal according to the introduction of these information. Of course, these introductions of silicon metal is not comprehensive, if you are interested in silicon metal, want to know more information about the silicon metal, on the one hand can log in our company website to consult relevant information, on the other hand can directly dial the hotline my company to discuss cooperation, therefore, welcome new and old customers contact with my company, my company will do our best to meet your requirements.
