Silicon nitride bricks are common on the market, and they have a significant role.
Silicon nitride bricks are common on the market, and they have a significant role. Although we often see them, many people are not very familiar with their properties. Let me give you a brief introduction. If you're interested, let's take a look together. This will help you avoid being misled when purchasing in the future.
The main components of silicon nitride bricks during production are magnesia and chromium trioxide. Reputable manufacturers mainly use Si3N4 as the main component of this special refractory material. These silicon nitride bricks are popular in the market because of their many advantages, such as high refractoriness, high-temperature strength, and strong resistance to alkaline slag erosion. They also have excellent thermal stability and are adaptable to acidic slags. Their flexural strength can reach 200-700 MPa, oxidation resistance temperature is 1400℃, and in a reducing atmosphere, it can reach 1870℃. Room temperature resistivity is 1.1 × 10^14 Ω·m. They are produced using silicon powder nitridation followed by sintering or hot pressing. These are the basic properties of silicon nitride bricks. As a manufacturer, we welcome you to call us for inquiries, and those who need to order can also purchase here. The quality of our products is guaranteed, and users can use them with confidence.
After understanding the characteristics of silicon nitride bricks, let's look at their production methods. This product is mainly produced using silicon powder nitridation followed by sintering or hot pressing. The production process of silicon nitride bricks is similar to that of magnesia bricks. In order to eliminate the combination of MgO and Cr2O3, Al2O3, or direct combination of silicon nitride bricks during firing. They are used in many places, such as aerospace, metallurgy, machinery, and semiconductor industries. Our company was established in 2000 and is an enterprise with an annual output of 3000 tons of various high-end refractory materials and an annual output value of 50 million.
