چکیده
|
In this study, boron carbide was synthesized using mesoporous carbon cmk-1, boron oxide, and magnesiothermic reduction process. the effects of temperature and magnesium grain size on the formation of boron carbide were studied using nano composite precurser containg mesoporous carbon. samples were leached in 2m hydrochloric acid to separate mg, mgo and magnesiumborat phases. sem, xrd and xray map analysis were caried out on the leached samples to characterize the boron carbide. results showed that the reaction efficiency developed in samples with weight ratio of b2o3:c:mg = 11:1.5:12, by increasing the temperature from 550 to 650 °c and magnesium powder size from 0.3 µm to 3 µm.
