Abstract: Cordierite-Mullite based kiln furnitures are widely used in fast-firing of ceramic products because of their low thermal expansion which confer them a very good ability to thermal shock resistance. Difference in CTE of constituent phase can develop damage during thermal cycling due to internal stresses. Increase in industrial competitiveness leads to the development of new means for e...

Two FCC spent catalysts with different amounts of La2O3 and similar Al2O3/SiO2 ratios the corresponding residues an optimized process La-extraction are studied. The potential powders as feedstock for mullite refractories is established. four have been fully characterized – chemical composition, crystalline phases, particle size, specific surface area, porosity, morphology. Their thermal evoluti...

The objective of this work is to obtain a multifunctional ceramic composite material at low cost with improved properties and that can be used in many structural applications like: electrical, refractory support tribological elements. A mullite-alumina were prepared by using Algerian kaolin amorphous aluminum hydroxide as starting materials. Two mixtures varying the content 61.5% 50 wt %. an ab...

Mullite (3Al2O3·2SiO2) is an aluminosilicate characterized by excellent physical properties, which makes it important ceramic material. In this way, ceramics based on mullite find applications in different technological fields as refractory material (metallurgy, glass, ceramics, etc.), matrix composite materials for high temperature applications, substrate multilayer packaging, protective coati...
