<p>A heat-insulating refractory material which can produce a given heat insulating effect without using ceramic heat-insulating fibers having problems in environmental hygiene and by using organic fibers only to such an extent as to enhance the adherability in the spraying work. The material comprises 2-50 wt.% of foaming material which foams at 400-1, 500 °C and 98-50 wt.% of refractory powder and further contains 20-250 wt.% (in terms of outer percentage) of a liquid binder.</p> |
