High temperature resistance and thermal conductivity of silicon metal powder
- 2019-03-30-

Due to the small amount of silicon metal naturally formed, most of the silicon metal in life is processed by man. Silicon Metal has a strong hardness and can be used as an important abrasive. But different from other ordinary abrasive silicon has a variety of properties, can be applied to various fields, it has high temperature resistance, thermal conductivity, electrical conductivity and so on. The following is an introduction to the properties of silicon metal and its basic structure.

Metallic Silicone PowderWith high temperature resistance and thermal conductivity, it has become one of the preferred kiln materials for tunnel kiln or shuttle kiln, and its conductivity makes it an important electric heating element and so on. Silicon metal is a typical stable compound of covalent bonding. Theoretically, silicon metal is stacked from SiC tetrahedron, except for parallel or anti-parallel combinations. SiC has 75 variants, all of which can be divided into crystal system, six square crystal system and rhomboid crystal system. Α-SiC is a high temperature stable type, β-SiC is low temperature stable type. Β-SiC can be converted to Α-sic,β-sic in 2100~2400℃ at a temperature of around 1450 ℃ by a simple silicon and carbon mixture. The multi-body analysis and quantitative determination of SiC microscopy can be carried out by transmission electron microscope and X-ray diffraction detection technique. In order to distinguish between different structures, there is a need for a corresponding naming method. Naming methods commonly used: the low temperature type of cubic silicon metal is called Β-sic, while the remaining six square, rhomboid cell structure is all called Α-sic. This naming method does not correspond to the practice of phase law and the nomenclature of mineralogy, but it is quite popular because it is very convenient.

The above is a description of the nature of silicon metal and its basic structure, our company produces a large number of silicon metal, if you want to deepen the understanding of silicon metal or need to buy if you can call us, you can also visit our official website for online trench, we will be patient to answer all sorts of puzzles for you, if you want to buy silicon metal, We will also provide you with high quality silicon metal to meet your needs.

Quanzhou Industrial Co., Ltd., founded in 2004, the office headquarters is located in the beautiful ancient city of the cross-strait, the beginning of the Maritime Silk Road: "Quanzhou."

WILLINGT Industrial Co., Ltd. China's professional silicone ash manufacturers, with Advanced micro-silica powder (silica ash) capture technology and equipment, for large-scale production and processing of different specifications of theMicro Silicone PowderProducts, the annual output of a total of more than 100,000 tons. Its sales subsidiary, Veolia Import & amp; Export Co., Ltd., early focus on the export market, has become a large number of customers in the Middle East, India, South Korea, South America and other regions of important partners, and radiation to Japan, Australia, Southeast Asia and other regions. With the domestic materials began to attach importance to and application of micro-silica powder, 2011 years later the company set up a domestic trade department, began to build a heavy hand to create an internal market, over the past few years with a number of domestic companies to reach an important partnership, industry coverage to concrete, refractories, flooring, mortar, ceramics, rubber, plastics and other fields.
