<p>Disclosed is a foamed ceramic material having a relatively small and uniform cell structure. The material is suitable for structural or insulating purposes. A continuous process for producing the foamed ceramic material comprises dropping a bloatable ceramic composition, in particulate form, through a heated zone thereby fusing and bloating the particles, and subsequently collecting the fused particles. To produce the desired cellular structure, the process does not fully bloat the particles during dropping, thereby delaying part of the bloating of the particles until after they have been collected as an agglomerated slab.</p> |
