Premixed Silica Ramming Mass with Boron Oxide
A Premixed Silica Ramming Mass with Boron Oxide can safely be used up to a very high operating temperature. It expands very little so it is superior to both alumina and magnesia to resist thermal shocks. Secondly its cost is very low in comparison to alumina and magnesia. The silica ramming mass is made of high purity microcrystalline quartz sand, powder, adding high temperature sintering flux and mineralizes. The Premixed Silica Ramming Mass with Boron Oxide is very effective and useful.
