Mullite Whiskers and Mullite-whisker Felt [PDF]
The Naval Surface Warfare Center has developed processes for the preparation of mullite (3(Al2O3)(dot)2(SiO2)) whiskers and mullite-whisker felt. Three patents on the technology were issued in 1990.

Porous Mullite Ceramics Formation and Modification with Some Additives
Development of modern technologies requires the production of materials with perfect and sometimes universal properties. Favorable refractoriness at temperature above 1580oC can be achieved when raw materials such as kaolin, alumina and silica were mixed

Porous Mullite Ceramics Formation by Slip Casting of Suspension of Raw Materials
Development of modern technologies requires the production of materials with perfect and sometimes universal properties. Mullite and mullite-corundum ceramics are the examples of such materials, which were known already in medieval Europe and whose ...

Influence of Thermal Treatment on Kankara Kaolinite [PDF]
In this work, the influence of thermal treatment on the structure of Kankara kaolinite was studied for the first time, using X-ray diffractogram (XRD), EDX, NanoSEM, FTIR-Attenuated Total Reflectance, DTA/TGA and BET surface area measurements.

Effect of Fe2O3 on Compressive Strength and Microstructure of Porous Acicular Mullite
Porous acicular mullite was fabricated at 1300 °C starting from Al2O3 and mixture of SiO2 and MoO3 obtained by previous oxidation of waste MoSi2. It was found that the presence of MoO3 favors formation of acicular (prism-like) mullite grains with sharp ...

Development of Mullite and Cordierite Crystalline Phases in Ceramics from Mixed Compositions
Development of ceramics with the prevailing mullite or cordierite crystalline phases is greatly dependent on the raw materials used. The purpose of this research is to examine the process of mullite and cordierite development from mixed compositions ...

Comparative study of conventional and microwave sintered mullite fibres: structural study
Mullite fibres were synthesised from a mixture of aluminium, aluminium chloride and acidic silica solutions as monophasic salts using a sol-gel technique. The viscosity and rheological behaviour of the mullite precursor sol were examined.

Effect of SiO2 on the Properties of Porous Corundum-Mullite Ceramic
The aim of this work was to investigate the influence of different ratio of kaolin, alumina with different grain size and silica as raw materials on mullite formation and its quantity in our ceramics, improve its properties by doping materials, method of
