This Small Business Innovation Research (SBIR) Phase I Project is focused on research to develop reinforced silicon carbide hollow spheres. This effort will apply a modified version of its proprietary hollow sphere production process in combination with novel materials. Novel characteristics resulting from the hollow sphere structure to be realized include: low cost bulk production of individual loose hollow spheres, uniform shape, uniform dimensions, dimensional stability, and low apparent density. Additionally, the hollow spheres will possess the important structural and thermal characteristics of silicon carbide including extreme hardness, high thermal conductivity, low thermal expansion coefficient, thermal shock resistance, high abrasion resistance, high melting point, and high resistance to oxidation or corrosion caused by other materials. These hollow spheres will ultimately be used to form continuous complex net shapes. The broader impact/commercial potential of this project will be the availability of lightweight, high-strength, high-temperature material structures not previously possible. Hollow silicon carbide spheres have commercial potential for high-performance applications, especially for net shape superstructures in supersonic and hypersonic aircraft, spacecraft, and missiles. These materials find specific applications in high-temperature environments, such as the exterior surfaces of space reentry vehicles, inside combustion chambers, and as nozzles in jet engines, rocket engines, and power generators. Hollow silicon carbide spheres have applications that include thermal insulation, impact absorption (armor), catalyst support, metal and gas filtration, automotive heat engines, and mechanical seals. The knowledge generated about silicon carbide during this project can also be transferred to other related materials such as boron carbide.

该小型企业创新研究（SBIR）第一阶段项目的重点是研究开发增强碳化硅空心球。 这项工作将采用其专有的空心球生产工艺的修改版本，并结合新材料。由待实现的空心球结构产生的新特性包括：单个松散空心球的低成本批量生产、均匀的形状、均匀的尺寸、尺寸稳定性和低表观密度。 此外，空心球将具有碳化硅的重要结构和热特性，包括极高的硬度、高导热性、低热膨胀系数、抗热冲击性、高耐磨性、高熔点和对由其它材料引起的氧化或腐蚀的高抗性。 这些空心球最终将用于形成连续复杂的网状结构。该项目更广泛的影响/商业潜力将是以前不可能的轻质，高强度，高温材料结构的可用性。 碳化硅空心球具有高性能应用的商业潜力，特别是用于超音速和高超音速飞机、航天器和导弹的净形上层结构。 这些材料在高温环境中有特定的应用，例如空间再入飞行器的外表面，燃烧室内部，以及喷气发动机，火箭发动机和发电机中的喷嘴。 空心碳化硅球的应用包括隔热、冲击吸收（装甲）、催化剂载体、金属和气体过滤、汽车热力发动机和机械密封。在此项目中产生的有关碳化硅的知识也可以转移到其他相关材料，如碳化硼。
