High-Purity Magnesium Oxide
Product Description
Introduction
Magnesium oxide is a high-purity, low-impurity MgO material specifically designed for use in the electronics, microelectronics, and optoelectronics fields. Compared to standard industrial-grade MgO, it features stricter purity requirements, superior electrical performance, and enhanced thermal stability. Key characteristics include high purity (≥98.5%), exceptionally high resistivity (>10¹² Ω·cm), and outstanding thermal conductivity (>40 W/m). Magnesium oxide is widely utilized across various industries, including food processing, electronic components, batteries, and rubber manufacturing.
