Development of ceramic cutting tools for future application on dry machining
(2010-12-15)
Advanced ceramic materials constitute a mature technology with a very broad base of current and potential applications and a growing list of material compositions. Within the advanced ceramics category, silicon nitride ...
EFFECT of DIFFERENT SOLID AMOUNTS IN THE PHYSICAL and MICROSCOPICAL PROPERTIES of SiC POROUS CERAMICS
(Trans Tech Publications Ltd, 2008-01-01)
The presence of pores in ceramics is directly related to the chosen forming process. So, in the starch consolidation method, the ceramics show, after burning, pores with morphology similar to that presented by this organic ...
Study of ceramic block manufacture with the addition of waste from iron ore extraction
(Trans Tech Publications Ltd, 2014-01-01)
This work is intended to study the possibility of adding an amount of waste from iron mining in the ceramic mass. Clay and coal, from Vale do Paraiba, Sao Paulo, Brazil, were used in this research. These raw materials are ...
