difference Alumina silicate fire brick high alumina brick Element The main components are aluminum oxide (Al₂O₃) and silicate The main component is alumina (Al₂O₃), the content of which is usually above 48%. performance Refractoriness, refractoriness under load, slag resistance, thermal shock resistance and other properties will vary depending on the specific chemical composition and manufacturing […]

Before we know how heavy a refractory brick is, let’s first understand how to calculate the weight of a refractory brick. The following formula is an example: Calculation formula for refractory brick weight: m = ρv (mass = volume × density) Calculation example of refractory brick weight: Take SK-32 refractory brick, T-3 straight standard brick […]

Difference Mullite Cordierite Ingredients The main component is island aluminum silicate, the mineral composition is mainly sillimanite, and it also contains a small amount of quartz, biotite, phlogopite, chlorite, etc. The main chemical components are magnesium aluminum silicate, in which the magnesium element can be replaced by a small amount of manganese, and the aluminum […]

Silicon carbide is an important raw material for refractory materials. It is often used to manufacture refractory materials, such as silicon carbide bricks, silicon carbide castables, silicon carbide combined with silicon nitride bricks, etc. The reason why it can be used as a raw material for refractory materials is mainly because of its obvious advantages. […]

Application of 70 high alumina bricks in glass kilns: Application area Function Specific role Pool walls and bottom Withstands corrosion and chemical reactions from high temperature molten glass Protect the pool wall and bottom from erosion by glass liquid and extend the life of the furnace Flame Space Resistant to erosion and thermal stress from […]

Difference Bauxite Calcined bauxite Ingredients and structure: Bauxite is a natural aluminum ore whose main component is aluminum oxide (Al2O3), and usually contains impurities such as iron oxide, silicon dioxide, and titanium oxide. After bauxite is treated by high-temperature calcination (heating), aluminum hydroxide (Al(OH)₃) is converted into aluminum oxide (Al₂O₃), and impurities may be decomposed […]

Castables (refractory castables) can be divided into many types according to their constituent materials, use environment and performance requirements. The following are some common types of castables: 15 common types of castables High-alumina castables: Contains a high proportion of alumina (Al₂O₃), has high refractoriness and slag resistance, and is suitable for high temperature environments. Clay […]

Mullite is an important refractory material widely used in high-temperature industrial environments. Although mullite insulation bricks and mullite bricks are both mullite materials, they have significant differences in composition, structure, performance and application. Here’s a detailed comparison of them: Composition and structure Mullite insulation brick: It is mainly composed of mullite (Al₂O₃-SiO₂) and usually contains […]
