Product description of Silica mortar
Silicon mortar is an uncertain refractory material used as a joint in refractory masonry. It consists of a refractory powder, a binder and a mixture in a certain proportion of particles and is mixed with water or liquid binder to form slurry. Silicon mortar uses silicon powder or a portion of silicon powder as the main material. The binder can be soft clay or a chemical binder.
Features of Silica mortar
High bond strength
High fire resistance
Good load softening performance
Good construction performance.
Application of Silica mortar
Silica mortar is mainly used for masonry and repair of hot air stoves, coke ovens, glass ovens, acid ovens, etc., and other industrial silicon brick stoves.

Silica mortar for coke ovens
Silicon coke oven mortar is made from natural high silicon soil containing more than 97% SiO2 and other auxiliary materials and special additives.
Silicon coke oven mortar is made from natural high silicon soil containing more than 97% SiO2. The silicon mortar has a naturally dispersed fineness. In the meantime, other auxiliary materials and special additives are added for manufacturing.
Advantages of Silica mortar
- Good construction performance, which can ensure the bonding time of masonry.
- The high-temperature bearing capacity and thermal stability coefficient are consistent with those of silicon bricks, without fracture, effectively extending the service life of the furnace body.
