Glass Grade Magnesium Oxide (MgO) – Product Introduction

1. Product Overview

Glass Grade Magnesium Oxide is a high-purity MgO specially designed for glass manufacturing. With low impurities, controlled particle size, and excellent thermal stability, it is widely used in high-end glass applications such as electronic glass, high-transparency glass, optical glass, tempered glass, and specialty glass.

2. Main Functions in Glass Production

  • Network Modifier: Improves the glass structure and enhances chemical stability.

  • Enhances Mechanical Strength: Increases bending strength, impact resistance, and compressive strength.

  • Improves Thermal Shock Resistance: Provides better stability during rapid temperature changes.

  • Reduces Melt Viscosity: Enhances melting efficiency and reduces energy consumption.

  • Improves Optical Performance: High-purity MgO reduces bubbles, streaks, and discoloration, ensuring higher transparency.
