white fused alumina (WFA) micro powder is available in spherical forms, which are categorized into two main types based on production processes and roundness, each suitable for different applications and cost considerations. Spherical Types and Production Processes Near-spherical/quasi-spherical WFA micro powder: Produced via autogenous grinding shaping or jet milling. It has a moderate roundness (0.7–0.8)

White fused alumina micro powder is not available in a flat form as a standard product. Its production process—melting high-purity alumina in an electric arc furnace, followed by cooling, crushing, shaping, and classification—results in angular, blocky, or near-spherical particles rather than flat, plate-like crystals. For flat/plate-like alumina micro powder, you should opt for tabular alumina fine

The type of white fused alumina suitable as a sandblasting abrasive is mainly determined by the purity grade and particle size specification of the product, which can be selected according to different sandblasting requirements such as processing precision, workpiece material and cost budget. The specific suitable types and their application scenarios are as follows: By purity grade High-purity white

The ball milling toughness and fracture resistance of white fused alumina (WFA) are directly positively correlated, inherently homologous, but distinct in evaluation dimensions—ball milling toughness serves as a standardized quantitative indicator to measure fracture resistance, while fracture resistance is the core mechanical property reflected by ball milling toughness. Both originate from WFA’s intrinsic material characteristics, with

White fused alumina (WFA) plays a critical role in steel ladle furnaces (SLF) as a high-performance refractory material, primarily used in linings and functional components to withstand harsh operating conditions. Its core functions revolve around protecting the furnace structure, ensuring steel quality, and extending service life, with specific roles detailed below: 1. Refractory Lining for

Measuring the ball milling toughness of white fused alumina (WFA) is standardized by national/international protocols, focusing on quantifying its resistance to fragmentation during ball milling. Here’s a step-by-step guide based on core standards like GB/T 2479-2022 (China) and relevant industrial practices: 1. Core Test Standard & Principle Reference Standard: Primarily GB/T 2479-2022 Abrasive—White Fused Alumina (China) or

  White fused alumina was made from the high quality alumina by melting above 2200℃ in the electric arc furnace and cooling. White fused alumina is white with the main crystal phase alpha-Al2O3. White fused alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume

Fixed furnace white corundum and dumping furnace white corundum differ in the following aspects:   Production process Fixed furnace: In the production of fixed furnace white corundum, the raw materials are placed in a fixed furnace for smelting. After smelting, the furnace body does not move, and the corundum is cooled and solidified in the

Yes, white corundum can be used for sandblasting high-speed steel (HSS) products, but its application requires careful matching with the material properties of HSS (high hardness, high toughness, often used for precision components like cutting tools and molds) and sandblasting objectives (e.g., removing oxide scales, deburring, or surface roughening for pretreatment). The right type, grit size,
