Microporous aggregates are the key to the lightweight design and preparation of refractories
for the working linings of the high temperature furnaces. In this work, the lightweight MgO …

In this work, microporous MgO refractory aggregates with nano-sized pores were prepared
by in situ decomposition method using Mg (OH) 2 as raw material. The effects of firing …

Abstract Microporous MgO-Mg (Al, Fe) 2 O 4 refractory aggregates were prepared using
magnesite, Al (OH) 3 and Fe 2 O 3 applying an in-situ decomposition synthesis method. At …

Abstract Six microporous MgO‐Al2O3 refractory aggregates were prepared with Al (OH) 3
and two different types of magnesite powders via an in‐situ decomposition pore‐forming …

MgO-MgFe 2 O 4 refractory aggregates with high closed porosity were fabricated using MgO
