Leadsun Refractory mortar is an amorphous refractory material used as a refractory masonry joint. Joint material. By a certain proportion of refractory powder and binding agent, admixture, water or liquid bond into a slurry.

Refractory slurry powder can be used to select a variety of refractory raw materials, sintered full of clinker and other volume stability. The size of powder material depends on the use of the requirements, the limit of grain size is generally less than 1mm, and some less than 0.5mm or more fine .
