Magnesia brick

Magnesia brick is a basic refractory brick, also named periclase brick. Its performance is usually determined by the purity of raw materials and it can operate in various scenarios.

Other name: Magnesite brick, MgO brick

Model Number: HCR M91,HCR M93,HCR M95,HCR M97

Certification: ISO9001-14001

Magnesia brick

Introduction

Periclase is magnesia brick's main crystal phase. Magnesia brick uses high purity magnesia sand as its raw material. And its thermal shock resistance is not so good, same with water resistance. Magnesia brick cannot directly touches silica brick under high temperature since magnesia brick's acid slag resistance not so well.

Features

1. High electric conductivity under high temperature
       2. Good thermal conductivity
       3. High refractoriness
       4. Good alkali slag resistance
