This paper describes the different properties of boron carbide powders produced respectively in vertical smelting furnace (called powder A for short) horizontal smelting furnace(called powder B for short).Comparison and analysis are also conducted on ceramic articles made with both powder A and powder B. The results show that, ceramic articles made with boron carbide powder A has higher hardness and higher density than those made with powder B. The working life of blasting nozzle made with powder A can last 800～1000h.
