Refractory Materials for Electrolytic Cell

Introduction

New type anti-permeation brick is used as the block layer of electrolytic cell with permeation resistant castable, can stop the permeation from Na, Naf and cryolite solution to soaking layer, keep the protecting layer from erosion, make the insulation capacity lasting to make the electrolytic cell in normal use, extend its working life.

Features:

1: High refractoriness

2: Excellent anti-permeable performance

3: High strength
