Composition: andalusite-mullite aggregates and fines. High temperature sintering (> 1450°C) gives the brick interesting mechanical and chemical properties! Andalusite = stone containing silica and alumina. Its composition makes it a material of choice for the manufacture of refractories. 25% of…

A refractory material is a material that must withstand temperatures above 1500°C without softening or sagging under its own weight. A refractory material consists of a skeleton of aggregates (300 µm-6mm) bound by a matrix of fine particles ( <…
