two vessels from different sites of the iranian plateau, dating to the late 4th or early 3rd millennium bce are presented aspalaeotechnological case studies. in the fractures of the vessels’ walls, interfaces left by added clay parts (enhanced inthe two illustrations) are quite recognizable. it is proposed that in both cases potters, in order to construct the bases, usedto make bowls comparable...

The technology of hot-pressed Cr(2+):ZnSe ceramic preparation is reported. Comparative gain-switched lasing of hot-pressed ceramic and CVD grown Cr(2+):ZnSe samples with slope efficiencies up to 10% and output energies up to 2 mJ were demonstrated. This is a milestone in the development of future large scale mid-IR laser systems based on ceramic TM(2+):II-VI materials. This evolving technology ...

In this paper, regarding to the fragility and surface erosion problems of Foshan ceramics, we discussed the methodology and technology of 3D reconstruction and virtual demonstration for Foshan ceramic object and cultural relics. We adopted Reverse Engineering technology to rebuild the shape of object by capturing point-cloud data from different angle, encapsulating and fitting these data into t...

The design of ceramic chemical microreactor for the production of hydrogen needed in portable polymer-electrolyte membrane (PEM) fuel cells is presented. The microreactor was developed for the steam reforming of liquid fuels with water into hydrogen. The complex three-dimensional ceramic structure of the microreactor includes evaporator(s), mixer(s), reformer and combustor. Low-temperature co-f...

Introduction Over the last twenty years, a great advancement in knowledge and technique for fine ceramics has been made in China. Although there is a long history of creating traditional ceramic and its culture in venerable china, the research and production of advanced ceramics on a large scale was started merely from 70th of last century. By now, there are more than 100 universities and resea...

In this research, an ancient Iranian ceramic technology, which was published previously for the first time, has been used to produce various colored ceramic glazes.  The color of such ancient glazes was always blue and the suitable body for that is unique due to high quartz content. There is no report of other color productions in productive workshop and scientific publications. The basic purp...

The paper has analyzed and digested the related literatures from home and aboard, summarized techniques and theoretical methods of the relevant prototype systems. Based on the understanding of the present situation of the domestic and foreign sketches technology application basis, through the existing ceramics product design process and production process flow of the detailed ceramic products o...

Powder injection molding (PIM), which encompasses metal injection molding (MIM) and ceramic injection molding (CIM), is a net-shaping process which enables large scale production of complex-shaped components for use in a diverse range of industries. It combines plastic injection molding techniques and performance attributes of ceramic and metal powders. Ceramic injection molding (CIM) uses cera...

The use of CAD/CAM technology has allowed the fabrication of ceramic restorations efficiently and with predictable results. Lithium disilicate is a type of glass ceramic material that can be used for the elaboration of laminate veneers, being monolithic restorations which require characterization through a covering ceramic in order to achieve acceptable esthetic results. The next case report sh...
