Green Silicon Carbide Properties, Applications and Production Process

Introduction

Green silicon carbide is made of petroleum coke and high quality silica as the main raw material, adding salt as an additive, and smelted by resistance furnace at high temperature.

Production Process

Green silicon carbide is used for processing cemented carbide, glass, ceramics and non-metallic materials, as well as for semiconductor materials, high-temperature silicon-carbon rod heaters, far-infrared source substrates, etc. Green silicon carbide is manufactured in the same way as black silicon carbide, but the purity of the raw material used is higher, and it is also formed at a high temperature of about 2200°C in a resistance furnace, green, translucent and hexagonal in shape, with a higher Sic content than black.



Applications

Green silicon carbide is an inorganic salt compound with the following applications.

1, applied in the non-ferrous metal smelting industry. With green silicon carbide high temperature, strength, good thermal conductivity and impact resistance, high temperature indirect heating materials.

2, applied in the steel industry. With green silicon carbide corrosion resistance, thermal shock wear resistance and good thermal conductivity to improve the service life of large blast furnaces.

3、Application in metallurgical ore processing. Green silicon carbide has strong wear resistance, hardness second only to diamond, is the ideal material.

4、Applied to the building materials ceramic grinding wheel industry. Use its characteristics, thermal conductivity, thermal radiation and high temperature strength to make plate kiln. It can not only reduce the kiln capacity, but also improve the installed capacity of the furnace and product quality and shorten the production cycle. This is also ideal for indirect material sintering ceramic glaze baking.

5, the application of energy saving. Use its good thermal conductivity and thermal stability to make heat exchangers, saving 20% of fuel consumption and 35% of fuel and increase productivity by 20-30%.

How to improve the durability of silica fume concrete?

Image
  There are many factors to measure the quality of concrete performance, durability is one of the very important indicators, if the durability is not enough, will lead to serious consequences. Thus, in the concrete configuration, how to improve the durability of concrete is a problem that engineers have been thinking about, the following we will understand some of the factors that affect the durability of concrete. The use of high-grade cement There are many factors that affect the durability of  concrete , not only the impact of the concrete configuration process of adulterated substances, but also need to pay attention to the quality of cement, such as the strength of the cement in the configuration process, varieties, aggregates and other factors of its own. In the actual project, we should consider the specific situation, and through scientific testing, so that the concrete to achieve the required high strength, high durability and high fluidity. The preparation of high-st...

From Waste to Wonder: The Remarkable Journey of Silica Fume in Industry

Image
Introduction to Silica Fume Origin of Silica Fume Silica fume, also known as microsilica, is a byproduct of the industrial production of ferrosilicon and silicon metal alloys. It's a fine powder composed primarily of silica (SiO2) and forms when silicon and oxygen react at high temperatures. Originally considered a waste material, silica fume has since been recognized as a valuable resource for various industries. Properties of Silica Fume Silica fume possesses unique properties that make it particularly useful in industrial applications. It is a highly reactive pozzolan, which means it can form cementitious compounds when mixed with water and calcium hydroxide. It also has a very fine particle size, usually less than 1 micron, giving it a large surface area that helps improve bonding and packing in composite materials. How Silica Fume is Produced Collection and Processing During the production of silicon metal and ferrosilicon alloys, silica fume is generated as a byproduct in th...
