Pyrophyllite

Description

1. Product Overview
Pyrophyllite is a naturally occurring hydrous aluminum silicate mineral widely valued for its excellent thermal stability, low electrical conductivity, and superior machinability. It is extensively used in ceramics, refractories, paints, plastics, and rubber industries as a functional filler and performance enhancer. The key value proposition lies in its ability to improve product durability, reduce shrinkage, and enhance surface finish while lowering production costs. Strategically, pyrophyllite is essential for manufacturers seeking high-performance, cost-efficient raw materials in large-scale industrial applications.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Al₂Si₄O₁₀(OH)₂ (Hydrous Aluminum Silicate)
• Purity Level / Grade: Typically 85%–98% (industrial and high-grade variants available)
• Physical Characteristics:
  • Form: مسحوق (powder), lumps, or granules
  • Color: White, grey, or greenish
  • Particle Size: Customizable (micronized to coarse grades)
  • Density: ~2.65–2.85 g/cm³
  • Hardness: 1–2 on Mohs scale
• Packaging Options: 25 kg bags, 50 kg bags, jumbo bags (1 MT), bulk shipments
• Shelf Life: Indefinite under dry storage conditions

3. Core Industrial Applications
Pyrophyllite serves as a critical raw material across multiple industries:

• Ceramics & Refractories: Enhances thermal resistance, reduces warping, and improves mechanical strength in tiles, sanitary ware, and kiln linings
• Paints & Coatings: Acts as a functional extender, improving opacity, durability, and chemical resistance
• Plastics & Rubber: Functions as a reinforcing filler, improving dimensional stability and reducing production costs
• Foundry & Metallurgy: Used in mold and core production due to its low thermal expansion and smooth finish properties

Compared to alternatives like talc or kaolin, pyrophyllite offers superior thermal shock resistance, better machinability, and improved structural integrity, resulting in higher operational efficiency and reduced defect rates.
