Brown Fused Aluminum Oxide: An Overview

Image
Brown fused aluminum oxide , also known as brown fused alumina (BFA) or brown corundum, is a synthetic abrasive material made from the fusion of high-quality bauxite, coke, and iron filings in an electric arc furnace at high temperatures. It is a tough, durable, and hard-wearing material widely used in a variety of industries, including the abrasives, refractories, and surface finishing sectors. Properties of Brown Fused Aluminum Oxide Brown fused aluminum oxide is characterized by its high hardness (9 on the Mohs scale), high melting point (2050°C), and chemical stability. It has excellent thermal conductivity, high electrical resistivity, and a low coefficient of thermal expansion. These properties make it an ideal material for various applications requiring high-performance abrasives and refractories. Production Process of Brown Fused Aluminum Oxide Raw Materials The primary raw materials for producing brown fused aluminum oxide are calcined bauxite, coke, and iron filings. Calcined...

94% Undensified Silica Fume: A High-Performance Supplementary Cementitious Material

Image
94% Undensified Silica Fume (USF) is a highly effective supplementary cementitious material derived from the byproduct of silicon and ferrosilicon alloy production. It contains approximately 94% amorphous silica (SiO2) and possesses exceptional physical and chemical properties that make it a valuable addition to various construction materials, especially concrete and cement-based products. With a low bulk density ranging from 250 to 350 kg/m3, 94% Undensified Silica Fume is lightweight and easy to handle, resulting in reduced transportation costs. Its specific surface area, typically between 15,000 and 30,000 m2/kg, allows for a high pozzolanic reactivity that enhances the mechanical and durability properties of the final products. The key features of 94% USF include its ability to significantly increase compressive and flexural strength, reduce permeability, and enhance resistance to chemical attack and abrasion. The use of this material contributes to improved long-term performance ...

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...

Application of silica fume in wear-resistant floor

Image
 Wear-resistant floors are widely used in the ground of various buildings, parking lots, offices, hospitals and a large number of public places. Wear-resistant floors require high wear resistance, crack resistance, permeability, mold resistance, Corrosion resistance and other functions, let's take a look at the application of silica fume in wear-resistant floors. Silica fume for wear-resistant floor is mainly used in various anti-seepage and anti-impact parts, so what characteristics of silica fume can help wear-resistant floor realize these functions? Silica fume particles are very, very fine, the average particle size of each silica fume is 0.1um, and the average surface area is 15000m2/kg. After adding silica fume to wear-resistant floor materials, silica fume can be mixed into wear-resistant materials to increase wear-resistant materials. The density and strength of the silica fume have excellent wear resistance. At the same time, due to the uniform density of silica fume, the...
