The invention provides novel continuous porous foamed
ceramic and a preparation method thereof, and belongs to the technical field of
ceramic material preparation. The novel continuous porous foamed
ceramic is prepared from, by weight, 50-100 parts of dump
slag, 18-50 parts of clay and 0-10 parts of
bentonite; by means of the bubbling effect of sulfides of Mn and Fe in the dump
slag, the volume is enlarged uniformly, and the ceramic bubbles continuously; the novel continuous porous foamed ceramic which is light in weight, capable of absorbing water, high in strength, capable of insulating heat, free of crack and high in quality is prepared at low price; the prepared novel continuous porous foamed ceramic can serve as sound-insulating and sound-absorbing plates arranged on the two sides of an expressway; the service life of the ceramic plates is 10 times or above that of
metal materials, and the contribution to the society is huge; by utilizing 30% dump
slag discharged in manufacture of ball-milled
cast iron products in the wide range of manufacturing automobile engines,
cast iron tap-water pipes and the like as the
raw material, the waste is turned into wealth, so that the novel continuous porous foamed ceramic is low in cost.
