Porous silicon nitride-based drug delivery carrier Hicak, Michal; Medvecky, L’ubomir; Hnatko, Miroslav; Stulajterova, Radoslava; Giretova, Maria; Tatarkova, Monika; Lences, Zoltan; Sajgalik, Pavol Abstract Tetracalcium phosphate/monetite biocement was modified with the addition of 30 wt% highly porous silicon nitride/alpha-tricalcium phosphate (alpha-TCP) microgranules. The volume ratio of Si3N4 and alpha-TCP in microgranules was 1:1 and showed good… Continue reading Porous silicon nitride-based drug delivery carrier

Formulation of mixed alumina/kaolin systems : Application to the elaboration of multi-layer materials by co-pressing Rana Al Tahan Abstract Multilayer ceramic architectures generally exhibit improved mechanical properties in regards with individual monolithic constituents. In alumina-based materials, addition of kaolin can advantageously promote i) mullite crystallisation and ii) internal residual stresses by monitoring thermal expansion mismatch… Continue reading Formulation of mixed alumina/kaolin systems : Application to the elaboration of multi-layer materials by co-pressing

Modified Freeze-granulation method for fabricating Li2TiO3 ceramic tritium breeding pebbles Shufeng Zhang, Wei Lu, Youfu Jiang, Xinyu Gao, Delin Chu, Weihua Wang Abstract Lithium metatitanate (Li2TiO3) ceramic is an important candidate for tritium breeding material in fusion reactor blanket. Nevertheless, mass production has become an important factor restricting the application of Li2TiO3 pebbles. In this… Continue reading Modified Freeze-granulation method for fabricating Li2TiO3 ceramic tritium breeding pebbles

Enhancing the density and crush load of Li2TiO3 tritium breeding ceramic pebbles by adding LiNO3-Li2CO3 Yichao Gong, Qingze Na, Chao Dang, Yijiang Yang, Mingxiang Tang, Zhanwen Liu, Guojun Zhang Abstract The fabrication of Li2TiO3 ceramic pebbles with satisfactory density and excellent crush load while maintaining a fine grain structure is one of the research objectives… Continue reading Enhancing the density and crush load of Li2TiO3 tritium breeding ceramic pebbles by adding LiNO3-Li2CO3

Comparative sintering behaviour of MOX powders synthesized through the freeze granulation or dry-cogrinding routes Guillaume Bernard-Granger, Florent Lebreton, Laure Ramond, Marion Le Guellec, Gabriella Cunha Costa Miranda, Abibatou Ndiaye, Thierry Gervais Abstract Two MOX powders containing 11 mol% Pu/(U+Pu) have been synthesized using the freeze granulation or dry-cogrinding routes. The sintering behaviour of green compacts has… Continue reading Comparative sintering behaviour of MOX powders synthesized through the freeze granulation or dry-cogrinding routes

Optimization of freeze granulation and sintering behavior of MgO granules for thermal interface materials Hyojung Cho, Rokhyeon Kim, Haewon Jung, Joo-Hwan Han, In Chul Jung, Jungho Ryu Abstract Heat management of high-performance secondary batteries, used in various applications that require high charging and discharging rates, such as electric vehicles and electronic devices, has recently been… Continue reading Optimization of freeze granulation and sintering behavior of MgO granules for thermal interface materials

Design and Process Considerations in Spray Freeze Drying Bernhard Luy, Matthias Plitzko, Howard Stamato Abstract Dynamic spray freeze drying combines spray freezing and rotary freeze drying to generate homogeneous, free-flowing lyophilized beads as a bulk intermediate product. This allows for filling on demand, with choices in dose strength and combinations of multiple active materials. Thus,… Continue reading Design and Process Considerations in Spray Freeze Drying

Compactability and sinterability of alumina granules made by spray freeze granulation drying and spray drying Naoki Kondo, Akihiro Shimamura, Mikinori Hotta, Junichi Tatami, Shinya Kawaguchi Abstract The compactability and sinterability of alumina granules prepared by spray freeze granulation drying (SFGD) and spray drying (SD) were compared. The strengths of the granules made by SFGD and… Continue reading Compactability and sinterability of alumina granules made by spray freeze granulation drying and spray drying
