Abstract :

Production of insulating fire icks from mixture of two different clays (kaolin and plastic clay) with sawdust addition is investigated. Suitability of kaolin with different weight percentages of plastic clay (20 to 40%) and sawdust (17 to 27%) have been added into the insulating fireicks, wet milled, spray dried, shaped and fired at different temperatures (900 – 1200°C). The properties of the resultant material then determined, water absorption, porosity, thermal conductivity, modulus of rupture, and compressive strength. The results indicate that the thermal conductivity of the samples produced from two different clays with sawdust addition decreased from 0.1429 W/mk to 0.0417 W/mk. Samples were stable at high temperatures up to 1100°C. The high porous as well as good mechanical strength produced in this study can be used for insulation fire ick in high temperature application
