Heat-insulating refractory material

Refractory material and product thereof containing low-silica

The application by spraying on a ceramic furnace wall of a refractory spray material prepared by mixing a spray powder consisting of 100 pts. wt. a refractory aggregate of a predetermined particle size and 0.1-3 pts. wt. a curing accelerator with 0.5-5 pts. wt. a damping agent added thereto is accomplished with notably high levels of adhesiveness and uniformity without deteriorating the working environment with dust by a method which comprises performing said application while admixing the refractory spray material with a sodium silicate solution as a binder having a viscosity in the range of 3-10 cPs at 15.degree. C. and containing 2-8 wt. % Na.sub.2 O and 8-20 wt. % SiO.sub.2.
