It was found that the combination process of gas atomizing and sintering process is useful for mass production of high quality thermoelectric materials. Because those process is simple without mixing or grinding process and any kind of materials can be made as far as they can be melted in a same crucible in a same time. The mean diameter of gas atomized powder is less than 100 m, and also the inner structure of them is fine including every necessary element. Accordingly gas atomized powder can be sintered in a short time by both methods of spark plasma sintering and hot press sintering. Thermoelectric properties of materials that were made in this process were compared with the same kind of material which was made in laboratory scale. Substituted type materials attained almost aimed value of ZT, however filled type material could not get the same ZT value which was made in laboratory scale. One of the main reasons of low ZT value of p-type was considered to be concerned with excess antimony owing to large-scale production. Another reason was considered to be oxide effect that was introduced in the process of gas atomizing. These factors seem to be also important for n-type materials to get higher properties.","PeriodicalId":253439,"journal":{"name":"Eighteenth International Conference on Thermoelectrics.

While recent research on novel materials and low-dimensional structures raises the hope for improved performance, additional innovations are required to make solid-state cooling competitive. MCC is developing a novel implementation and operational paradigm for solid-state coolers based on transient operation of thermoelectric (TE) coolers and micro-electro-mechanical switch (MEMS) technology. Application of a short transient pulse on top of a steady state bias to a correctly designed TE cooler results in a temporary additional temperature drop. MEMS switches can exploit this effect by providing a thermal switch between the cold end of the TE cooler and the device to be cooled, only connecting them during repeated transient pulses. The objective of this work is to demonstrate the feasibility of the TE MEMS cooler concept by fabricating a prototype and achieving a cold temperature lower than the one achievable by steady-state operation of a thermoelectric cooler. In this paper we describe the general concept and report on the progress made to date.","PeriodicalId":253439,"journal":{"name":"Eighteenth International Conference on Thermoelectrics.
