Abstract

A flame spray mending material effective for applying a dense thermal spray mending layer to a silica brick wall of an industrial furnace, having a high crystallization ratio immediately after thermal spraying in a broad thermal spray condition, having an oxide concentration of 89% by weight or more of SiO,, more than 2.0 to 4.0% by weight of Na,O and/or more than 0.2 to 4.0% by weight of Li,O, having a 80% or more crystallization ratio after thermal spraying and 200 kgf/cm,or more compression strength. A slight amount of CaO may be present to make a flame spray mending material with an oxide concentration of 89% by weight or more of SiO,, more than 2.0 to 5.0% by weight of CaO, 0.5 to 4.0% by weight of Na,O and/or more than 0.2 to 4.0% by weight of Li,O, and 1.0% by weight of less of Al,O,.
