This study comprises a simple and innovative approach for the synthesis of á-alumina powders involving the use of the metal organic precursor aluminum formate Al(O2CH)3 and phase transformations...

A method for preparing sodium aluminate from basic aluminum sulfate (BAS) is presented. By this method, crystalline sodium aluminate could be obtained under mild conditions by heating sodium dawsonite...

One of the serious problems in Japan is the disposition of garbage and wastes because of the shortage of waste disposal sites. The recycling technology of sludge from water purification plant was...

This paper describes a method for producing submicron high-purity alumina. In this method amorphous basic aluminum sulfate (BAS) was prepared by homogeneous precipitation of aluminum bisulfite...

Aluminum Nitride (AlN) is a important substrate material in electronic devices. AlN powders can become contaminatedby oxygen i9f they come into contact with water or oxygen. Hydrolysis behaviour and...

An overview of bioceramics, their behaviour in the human body, the forms they can take and their functions is provided. In addition materials such as calcium phosphate materials, alumina, zirconia and...

Macroporous ZrO2 - Al2O3 mixed oxides containing different amounts of Al2O3 were prepared via colloidal processing using negatively charged polystyrene spheres as template and ultrafine particles of...

This research for Eco-materials focuses on the improvement of photo response of titania thin films. The goal of this research is to find a suitable substrate for decreasing the band-gap of titania, to...

A study was carried out on the hydroxyapatite/zirconia-base bi-layer to encapsulate substrates of 316L stainless steel for covering orthopedic prostheses. The coatings were produced by screen printer...

Porous ceramic foams have emerged as a viable alternative to refractory ceramic fibres since they were classified as carcinogenic. Hi-Por is a ceramic foam that has similar properties to FCFs without...
