Recycling of aluminum dross is a significant issue in domestic aluminum industry. In this study, formed ceramic materials were prepared using aluminum dross mixed with feldspar powders to investigate its application as industrial materials and utilization of aluminum dross. In the prepared sample, feldspar was melted at the sintered temperature, and its phase was trans-formed into amorphous, and spinel ($MgA1_2$$O_4$) phase in the dross was remained clearly. Density of the test specimen Increased from 0.91 to 0.65 gr/㎤ and water absorbance decreased from 2.5 to 1.7f% with increasing of sintered time at the sintered temperature $1220^{circ}C$ with composition of feldspar 55 wt%, dross 40wt% and bentonite 5 wt%. At the same experimental conditions, bending strength of the test specimen was 10.8 MPa, and heat conductivity was 0.34 W/m.K with sintered time 30 minutes.
