How to Optimize White Fused Alumina Particle Size Distribution for Better Grinding Performance

White Fused Alumina (WFA) is a high-purity form of alumina (Al₂O₃) produced through a fusion process that involves melting bauxite at high temperatures in an electric arc furnace. WFA is commonly used as an abrasive material due to its hardness and resistance to wear, making it ideal for various grinding, polishing, and cutting applications. It is essential in industries such as metalworking, ceramics, and automotive parts manufacturing.

The Best Types of Abrasive Grains for Refractory Castables in High-Temperature Kilns

Author: Leif Shi | DOMILL Abrasive Technology When it comes to high-temperature kilns—used in steel plants, ceramics, glass manufacturing, and incineration—the heart of long-lasting performance lies in the quality of the refractory castable. One key component often overlooked? The abrasive grains used as aggregates or fillers. These grains directly impact the thermal resistance, mechanical strength, and erosion resistance of the final castable. Having worked with refractory manufacturers for over two decades, I’ve seen firsthand how choosing the right abrasive grain can extend service life, reduce maintenance downtime, and cut costs in the long run. So let’s dive into the best abrasive grain options for refractory castables, and when to use each. Why Abrasive Grains Matter in Refractory Castables Refractory castables are a mix of ceramic aggregates, binders, and additives poured into shapes or applied in place to line kilns and furnaces. Abrasive grains act as structural skeletons, and their thermal properties define how well the castable performs in: High-temperature stability (1500–1800°C); Thermal shock resistance; Corrosion resistance; Erosion from hot gases or molten materials. Best Abrasive Grains for Refractory Castables Here’s a rundown of the most commonly used—and effective—abrasive grains for high-performance castables: 1. White Fused Alumina (WFA) Al₂O₃ content: 99.3%+...
