Synthesis of HfB2 Powders by Carbothermal Reduction
In this research, solid state carbothermal synthesis of HfB2 Nano powders was investigated. For this purpose, HfO2,H3BO3, carbon active or phenolic resin were used as raw materials for carbothermal reaction. After 2-4 hours of milling the raw materials by a planetary ball in an ethanol media, the mixture was heat dried and pressed in to disks under pressure of 20-30 bar. The disks were then pla...
متن کاملThe Preparation of Bamboo-Structured Carbon Nanotubes with the Controlled Porosity by CVD of Acetylene on Co-Mo/MCM-41
Bamboo-structured carbon nanotubes are grown on Co-Mo/MCM-41 catalyst in the temperature range of 873-973 K by thermal chemical vapor deposition of acetylene. This study shows that the purified carbon nanotubes have open tips and the metals of the catalyst are not encapsulated. Thus, the bamboo-structure seems to grow from the base. Pore size distribution of the product is quite narrow and ...
متن کاملMicrowave Absorption and Infrared Stealth Characteristics of Bamboo Charcoal/Silver Composites Prepared by Chemical Reduction Method
Bamboo charcoal coated with silver (BC/Ag) was prepared by activation and chemical reduction processes at different AgNO3 contents (10-30 wt.%). The spectroscopic characterizations of the formation processes of BC/Ag composites were studied using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. These composites were introduced in epoxy resin to be a microwav...
متن کاملPreparation of Bamboo-based Porous Carbons with Tunable Structure by Growing Carbon Nanofibers
The activated bamboo char (ABC) was available commercially and carbon nanofibers (CNF) were grown on its surface by a CVD method. The resultant composites were characterized by nitrogen method at 77K and scanning electron microscopy (SEM). The structure of bamboo-based porous carbon might be tunable by adjusting purposively the growth of CNFs. The CNF/ABC composite would combine the properties ...
