“…Meanwhile, as reported by Götze, quartz sand predominantly consists of silica so that it can used as reinforment to enhance the mechanical strength of composite [15]. Further, silica has also been widely used as reinforcement in several composites, such as leaves waste composite [6], mortar and concrete composite [16], leaves and paper composite [7] and also as filler in several electolye polymers [17].…”

Effect of turbulence modelling to predict combustion and nanoparticle production in the flame assisted spray dryer based on computational fluid dynamics AIP Conference Proceedings 1712, 040002 (2016) A solid waste composite was successfully made. Preliminary, the composite was synthesized using polyurethane (PU) as binder mixed with the solid waste using simple mixing method and then hot-pressed at at pressure of 4 metric-tons and temperature of 80 C for 20 minutes. To enhance its strength, quartz sand partilces with varied content then were added into the PU-solid waste mixture. From the compressive strength test, it was obtained that PU/solid waste composite with PU fraction (w/w) of 0.43 has optimum compressive strength of 38.91 MPa. Having been added quartz sand having average particles size of 0.94 m, its compressive strength attains maximum at 40.47 MPa for quartz sand fraction (w/w) of 4.27 x 10 -3 . The strength is comparable to that of clay brick, slate stone, sandstone, limestone, alder wood, aspen wood, black cherry and pine woods. Therefore, this composite is very adequate to compete the building materials such as the bricks, stones and woods.

“…Use of RHs to produce powder materials, including SiC, SiO 2 , Si 3 N 4 , Si, and activated carbon have been attempted (Ai et al 2013;Lee and Cutler 1975;Sun and Gong 2001), but industrial uses remain limited. RHs have also been used to produce porous SiO 2 /C composites or as fillers in the preparation of ceramic matrix composites by reaction of RHs ash with polysiloxane or melamine formaldehyde composites by compression molding (Chen et al 2013;Kumagai and Sasaki 2009;Schiavon et al 2009), but the mechanical properties of these composites were very poor. Recently, the authors used RHs as the raw material to produce mixtures of carbon and SiC containing SiC-whisker (SiC w ).…”

Dense silicon carbide (SiC) matrix composites with SiC whiskers and particles as reinforcement were prepared by infiltrating molten Si at 1550 °C into porous preforms composed of pyrolysed rice husks (RHs) and extra added SiC powder in different ratios. The Vickers hardness of the composites showed an increase from 18.6 to 21.3 GPa when the amount of SiC added in the preforms was 20% (w/w), and then decreased to 17.3 GPa with the increase of SiC added in the preforms up to 80% (w/w). The values of flexural strength of the composites initially decreased when 20% (w/w) SiC was added in the preform and then increased to 587 MPa when the SiC concentration reached 80% (w/w). The refinement of SiC particle sizes and the improvement of the microstructure in particle distribution of the composites due to the addition of external SiC played an effective role in improving the mechanical properties of the composites.

Liquid silicon infiltration (LSI), in which liquid Si infiltrates into porous preforms composed of carbon or mixtures of carbon and SiC powders, is a promising method to fabricate SiC ceramics. The process of infiltration results in formation of newly formed SiC grains by the reaction of Si with carbon. LSI is a simple fabrication technology that can fabricate dense SiC ceramics in a short time at a comparatively low temperature (Margiotta et al. 2010;Wang et al. 2004). The dimensional variation of the final product prepared by LSI is small. Such a near-net shape feature makes LSI an effective method in producing SiC ceramic parts with none or less expensive post-machining (Chen et al. 2002).In recent years, biological carbon-based precursors obtained via carbonisation of woods, bamboo coir, and cotton fabric have been investigated to fabricate SiC ceramics by LSI (Amirthan et al. 2009;Maity et al. 2010;Varela-Feria et al. 2008). Different from these biological plant materials, rice husks (RHs) are commonly used in low-value applications in agriculture such as fuel, or otherwise simply disposed as wastes.

Die Umwandlung von Biomasse in hochwertige Produkte hat in jüngster Zeit beträchtliche Aufmerksamkeit erhalten. Biomasse aus Reishülsen (“rice husks”, RH) wurde ursprünglich dazu verwendet, Schüttgüter für konventionelle Anwendungen herzustellen, während in den letzten Jahren daraus eine Vielzahl von modernen Nanostrukturen (NS) hergestellt wurden. RH‐basierte Nanostrukturen (RH‐NS) sind kostengünstig und umweltfreundlich, und sie haben viele Eigenschaften, die für Anwendungen in verschiedenen Bereichen vielversprechend sind. Basierend auf der einzigartigen Struktur und den Komponenten der RH wurde eine Reihe von neuartigen, auf Kohlenstoff/Silicium basierenden NS mit herausragenden Eigenschaften erschlossen, die mit herkömmlichen chemischen Reagenzien nur schwer zu synthetisieren sind. Hier werden neueste Forschungsergebnisse zu RH‐NS zusammengefasst, die sich auf Design, Herstellung, Eigenschaften und Anwendungen im modernen Energiebereich beziehen.
