Effect of Al4SiC4 on the Al2O3SiCSiO2C refractory castables performance

Ceramics International, 2012
Abstract Carbon-containing refractories are widely used in the steelmaking process due to their outstanding properties and, in order to improve their oxidation resistance, the so-called antioxidants have often been used. Al 4 SiC 4 is pointed out as a novel additive that presents suitable properties such as Al, but without its drawbacks.

SiC fines effects on the microstructure and properties of bauxite-based low-cement refractory castables

Ceramics International, 2019
In the present paper, the effect of silicon carbide (SiC) fines was studied on the phase and microstructural properties of bauxite-based low-cement refractory castables (LCC) at different firing temperatures.

Phase evolution with temperature in chromium-containing refractory castables used for waste melting furnaces and Cr(VI) leachability

Ceramics International, 2018
Highly corrosion resistant Cr 2 O 3 based refractory linings are required for waste melting furnaces due to the complex melting environment. However, these linings are susceptible to Cr(VI) generation during service.

Transient Properties of Refractory Castable with Hydraulic Binders

2014
Refractory castables based on hydraulic binders have a widespread use in aluminium casthouses (furnaces, launders, etc.). Their selection is based on properties such as corrosion resistance to molten metal, mechanical behavior and insulation. Few studies concern the hydric exchanges between the refractory materials and the surrounding atmosphere, while

Refractory castables for titanium metallurgy based on calcium zirconate

Materials & Design (1980-2015), 2018
Calcium zirconate (CaZrO3) is a promising refractory material to melt titanium alloys. Therefore the present study investigated refractory castables based on CaZrO3 to allow an upscaling to larger melting crucibles and refractory linings. The study first
