Heat Content of Calcium Ferrite Slag

Effects of vacuum infilteration dipping in calcium chloride and postharvest heat treatment on firmness and calcium content of apples

Effect of aging on Phosphorus removal of metallurgical slag and heat reactivation of aged slag

In order to examine the effect of ageing on P removal capacity, the phosphorus (P) removal capacity of three types of slag, argon oxygen decarburisation slag (AOD), blast furnace slag (BFS) and electric arc furnace slag (EAF), was examined after 0, 10, 13 and 19 months in batch experiments. The results showed that ageing reduced P removal capacity, e.g. by 78.4% for 19-month-old AOD slag. For B...

The Compressive Strength of Cement–Slag–Calcium Sulphoaluminate Ternary System

At present, there is an increasing interest on the use of calcium sulphoaluminate (C4A3$) in cement. In this paper, pure mineral of sulphoaluminate (C4A3$) was prepared in laboratory. Different dosages of steel slag and C4A3$ were blended into cement. The aim of this paper is to investigate the compressive strength of this ternary system. The test results show that the addition of C4A3$ can imp...

The Effect of Heat Treatment on Titania Slag

The paper embodies the influence of thermal treatment on the morphology, composition and leaching behaviour of titania slag. When Ti-slag was subjected to heat treatment, it developed pores and oxidized at high temperature. This slag consists mainly of a M3O5 phase with an orthorhombic structure. The decrepitation was studied by oxidizing the titania slag sample produced in a pot/muffle furnace...

Temperature dependence of magnetic properties of heat treated cobalt ferrite

This study demonstrates the effectiveness of heat treatment in optimizing the magneticproperties of cobalt ferrite, compared to other methods such as cation substitution. It also shows how the magnetic properties of the heat treated cobalt ferrite vary under differenttemperature conditions. Saturation magnetization increased more due to heat treatment than due to Zn-substitution; a cation subst...
