Introduction

The product is made by adopting high temperature electro-calcined anthracite coal as main raw materials, added with several kinds of super fine powder as additives, taking special technology to realize micropore. It is characterized by good thermal conductivity, alkaline resistance, anti oxidation, slag resistance, resistance against hot metal corrosion and micropores-formed.
