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 […]

Hot face insulation bricks and cold face insulation bricks both play a very important role in high temperature environments. They have similarities and differences. Let us learn about them together! Difference Hot face insulation bricks Cold face insulation bricks Purpose and location Directly in contact with high temperature flames or high temperature materials, usually used […]

Refractory Bricks Features: High temperature stability: Refractory bricks can maintain their shape and performance at extremely high temperatures and will not melt or deform easily. Mechanical strength: With high compressive strength and flexural strength, they are suitable for parts that need to bear weight or structural support. Chemical corrosion resistance: They have a certain tolerance […]

Silicon carbide (SiC), also known as silicon carbide or corundum, is a compound composed of silicon and carbon. Here are some key facts about silicon carbide: Structure: Silicon carbide has a variety of crystal structures, the most common of which are α-SiC and β-SiC. α-SiC has a hexagonal structure, while β-SiC has a cubic structure. […]

1. Preparation before construction Material storage: Refractory plastic cannot be piled in the open air and should be stored in a cool warehouse. If the ambient temperature is below 10℃, cold protection measures need to be taken. Equipment commissioning: Install the forced mixer in place and test run normally. Cleaning the site: Before construction, the […]

Refractory cement and refractory mortar are two different building materials that differ in composition, use, and performance. The following are their main differences: Refractory cement Refractory mortar Element Refractory cement is a special type of cement, the main component of which is calcium aluminate, and usually contains a certain proportion of alumina. It is made […]

Lightweight insulation brick The classification of refractory insulation bricks can be divided according to different standards. The following are some of the main classification methods: Classification according to material composition: Alumina insulation bricks (bubble alumina bricks, lightweight alumina bricks) Alumina silicate insulation bricks (high alumina insulation bricks, clay insulation bricks) Silica insulation bricks Magnesia insulation […]

Although both Bubble Alumina Brick and Hollow Alumina Brick are used for heat insulation and insulation in high temperature environments, they have the following main differences in structure, performance and use: Bubble Alumina Brick Hollow Alumina Brick structure The bricks contain air bubbles, which are usually formed during the production process by introducing air or […]
