Semi-acid Refractory

- Nov 02, 2018 -

Semi-acid refractories are refractory materials containing a relatively large amount of silica and alumina. It is one of the refractory materials. The main purpose is to make semi-silicon bricks. In order to alleviate the thermal expansion properties of the silica brick, in order to compensate for the re-combustion shrinkage and softening properties of the clay brick, a larger amount of clay-fired refractory brick is added to the quartz.

Its anti-slag properties are better, especially for acidic slag. Such as semi-silicon bricks, etc.
