Temperature effect on preparation of water-Storage ceramic foam with vanadium-titanium magnetite tailings

Abstract

Massive accumulation of vanadium-titanium magnetite tailings (VTMT)—a kind of common industrial solid wastes—will pose enormous harms to both ecological environment and economic development. Based on the preparation of water-storage ceramic foam by taking full advantages of 50 wt% VTMT and 50 wt% waste glass, the effect of sintering temperature on the sample performance was further investigated through a test, and the foaming mechanism at high temperature was deeply probed. The results show that as the sintering temperature rises, the bulk density and compressive strength of the sample gradually decline, its water absorption per volume reaches the maximum value and the average pore diameter inside the sample is gradually increasing. The optimal sinter temperature is 1,040 °C, and the water absorption, bulk density and compressive strength of the sample are 56.5%, 0.26 g/cm3 and 0.68 MPa, respectively.
