A surface-treating agent for a high-temperature refractory material, essentially consisting of 35.0 to 50.0 wt % of sodium silicate, 1.0 to 10.0 wt % of lithium compound, 1.0 to 10.0 wt % of alkali borate, 1 to 10.0 wt % of an organic silicone compound represented by the formula, R--Si(OH).sub.2 Na, wherein R stands for an alkyl group of 1 to 12 carbon atoms, and water and having a viscosity of not more than 100 cps at 20.degree. C., and a method for the surface treatment of a high-temperature refractory material, essentially consisting of rapidly spraying the treating agent mentioned above onto the surface of the refractory material when it is at a temperature in the range of 500.degree. to 1200.degree. C., thereby forming a layer of the treating agent in a molten state, and retaining the layer at a temperature of at least 1100.degree. C.
A surface-treating agent for a high-temperature refractory material, consisting essentially of 35.0 to 50.0 wt % of sodium silicate, 1.0 to 10.0 wt % of at least one lithium compound selected from the group consisting of lithium hydroxide, lithium carbonate, and lithium chloride, 1.0 to 10.0 wt % of an alkali borate, 1 to 10.0 wt % of an organic silicone compound represented by the formula, R--Si(OH).sub.2 Na, wherein R stands for an alkyl group of 1 to 12 carbon atoms, and water and having a viscosity of not more than 100 cps at 20.degree. C.
