Abstract

        In the present research , synthesis of  nano structure SiC in presence of high surface area of mesoporous carbon(CMK-1) were investigated. To synthesis SiC ,leached and cation exchanged zeolite were used with sucrose and mesoporous carbon. Samples with carbon ,type of carbon and processed zeolite ,fired at 700-750^oc  under argon diffrents of amount atmosphere with 5⁰C/min heating rate and soaking time about 3hrs were prepered.
XRD and XRF analysis were carried out on natural zeolite. To characterize the CMK-1 XRD,SEM/EDX with BET were used. Moreover to characterize ,leached and cation exchanged zeolite SEM/EDS and XRD analysis were used.
XRD results showed that the amount of mesoporous carbon as well as the type of processing of zeolite  had the main role in synthesis of high purrity SiCs. XRD and SEM/TEM studies showed that Nano structure of SiC was produced in the process.
