He examines the most commonly used qualities, highlighting their strengths and weaknesses, in order to make the correct choice according to existing stresses in the area. In addition, the latest generation of mullite is presented which, for its high level of mullitisation and small percentage of glassy phase, presents interesting chemical-physical characteristics that increase performance.
