The paper presents preparation of YAG precursor powders mixture with ability for the reaction sintering at lower temperature. The powder mixture was mechanochemically processed and characterized for the specific surface area and crystallinity (XRD). Sintering experiments were performed on the batched powders, mechanochemically processed powders and as-synthesised YAG powders. XRD measurements a...

Selective Separation Sintering (SSS) is a powder layer based Additive Manufacturing approach. SSS can fabricate high temperature ceramic and metallic parts at comparatively lower cost with high quality. In the printing process a dry powder of higher sintering temperature is deposited into the base material which makes up the part. The inserted powder defines the boundary of the part and separat...

producing parts with high density and improved mechanical properties is one of the most important aims of powder metallurgy process. there are many factors for attaining modified properties in sintered parts but among them controlling type and quantity of alloying elements and manufacturing parameters such as compacting pressure, sintering temperature are the most effective.in this research, tw...

A method for sintering nanoparticles by applying voltage is presented. This electrical sintering method is demonstrated using silver nanoparticle structures ink-jet-printed onto temperature-sensitive photopaper. The conductivity of the printed nanoparticle layer increases by more than five orders of magnitude during the sintering process, with the final conductivity reaching 3.7 × 10(7) S m(-1)...

In this work, a new way to fabricate nanoporous TiO2 photoanode by flash light is demonstrated. TiO2 nanoparticles are sintered on FTO glass by flash light irradiation at room temperature in ambient condition, which is dramatically simple, ultrahigh speed and one-shot large area fabrication process compared to a conventional high temperature (120 °C) thermal sintering process. The effect of the...

This study describes a conductive ink formulation that exploits electrochemical sintering of Zn microparticles in aqueous solutions at room temperature. This material system has relevance to emerging classes of biologically and environmentally degradable electronic devices. The sintering process involves dissolution of a surface passivation layer of zinc oxide in CH3 COOH/H2 O and subsequent se...

High voltage gradient ZnO-based thick film varistors were fabricated by low-temperature sintering. The effect of sintering temperature on electrical properties of thick film varistors was investigated. The voltage gradient of thick film varistors increased significantly to 3159.4 V/mm after sintering at 725°C for 30 min. The small average grain size with good grain boundaries was the origin for...

Tubular ceramic foams were prepared by using natural clay as starting material and 120 ppi polyurethane foam as template via polymeric sponge method. Samples were sintered with different temperatures from 1200°C to 1280°C. The result shows that 1250°C is the ideal sintering temperature where the highest compressive strength of 1.980MPa at 47.31% porosity is obtained. The highest value in compre...

This study investigates phase transformation and mechanical properties of porous NiTi alloys using two different powder compacts (i.e., Ni/Ti and Ni/TiH2) by a conventional press-and-sinter means. The compacted powder mixtures were sintered in vacuum at a final temperature of 1373 K. The phase evolution was performed by in situ neutron diffraction upon sintering and cooling. The predominant pha...

II-VI semiconductors form an important class of opto-electronic materials. CdSe is a promising material for the fabrication of photovoltaic devices. Polycrystalline CdSe films have been deposited onto ultra clean glass substrates by sintering process. The optical band gap of these films was determined by reflectance measurements in wavelength range 400-850 nm. The band gap of these films was ob...
