Antiwetting agents

Compounds containing magnesium, barium, calcium, and aluminium are the main antiwetting agents for the refractories for Al it is to some extent the consequence from the data appearing in Table 3.3. 

Barium alumina silicate celsian also may be an antiwetting agent, although is a lower degree than barium sulfate. Barium sulfate transforms into celsian in service in concretes and in phosphate-bonded bricks as well. Celsian is stable until 1,500 °C.
