Quartzite is a metamorphic rock composed mainly of quartz. It is far from ordinary—instead, it serves as a critical mineral resource supporting numerous industrial sectors. It forms through the regional metamorphic recrystallization or contact metamorphism of protoliths such as quartz sandstone, other siliceous rocks, or silica-rich rocks near magmatic bodies. Quartzite ore consists of cryptocrystalline

Fillers not only reduce production costs and increase profit margins but also enhance properties such as high-temperature resistance, corrosion resistance, surface hardness, strength, wear resistance, flame retardancy, and insulation to some extent. For plastics, there are commonly used fillers like glass fiber, calcium carbonate, glass microspheres, silicate minerals and titanium dioxide. Glass Fiber Glass fiber

NdFeB (neodymium iron boron) is characterized by its high hardness, strong magnetic properties, and vulnerability to oxidation. Producing ultrafine NdFeB powder requires specialized grinding equipment that offers efficient milling, precise particle size classification, and protection against oxidation through inert gas environments. Below is an analysis of the most suitable grinding mills for ultrafine NdFeB powder

In Part 1, we uncovered the secrets behind stronger and more cost-effective plastics, exploring the fundamental roles of calcium carbonate, talc, and wollastonite. But the world of plastic fillers doesn’t stop there. Now, let’s discover how materials like kaolin, mica and silica can be the key to your next innovative plastic compound. Kaolin Kaolin (Al₂O₃·2SiO₂·2H₂O),

Have you ever wondered why some plastic products outperform others in strength, durability, and cost-effectiveness? The secret often lies not in the base polymer itself, but in the sophisticated world of plastic modification through functional fillers. These mineral powders, when properly selected and incorporated, can dramatically enhance material properties while reducing production costs. In this

This article explores the critical role of aluminum powder in manufacturing aerated concrete blocks—a lightweight, energy-efficient building material. Specifically, we will examine how aluminum powder enables the formation of the material’s distinctive porous structure and review the grinding equipment offered by Epic Powder, a specialist in ultra-fine powder processing technology. Q1: Why is aluminum powder
