andalusite refractory bricks

Process Characteristics and Main Applications of Andalusite

by

The main reason for the industrial use of andalusite is its high temperature resistance. When andalusite is heated to 1350°C under normal pressure, it begins to transform into needle-shaped mullite parallel to the original crystal. Mullite crystal is the only stable form of aluminosilicate under high temperature, and its theoretical conversion rate is 87.64%. Processing … Read more

Application of Andalusite Refractory Bricks in High Temperature Kilns

by

Andalusite refractory bricks are suitable for use as refractory bricks for hot blast stove ceramic burners. By introducing andalusite and silicon micro powder of different grades and contents to improve its chemical mineral composition and improve the purity of raw materials. More importantly, the softening temperature under load, thermal shock resistance, and high temperature creep … Read more
