Manufacture of novel composition containing carbon and novel boron carbide
专利汇可以提供Manufacture of novel composition containing carbon and novel boron carbide专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a carbon-contg. composition giving easily fine boron carbide powder of high purity by blowing boric ester into hot gas contg. steam to produce mixed aerosol dispersoid contg. boron oxide and elemental carbon by decomposition and by subjecting the dispersoid to solid-vapor separation.
CONSTITUTION: Air is introduced into a furnace 1 from a duct 2, and a fuel such as methane is fed to a burner 3 and burned to generate hot gas contg. steam. Boric ester represented by the formula (where n is 1W3, and R is alkyl, cycloalkyl or aryl) is blown into the hot gas to produce mixed aerosol dispersoid contg. aerosol of boron oxide and aerosol of elemental carbon by a thermal decomposition reaction, and the dispersoid is discharged from a duct 5. It is sent to a solid-vapor separator such as a bag filter to capture a carbon-contg. composition, and this composition is calcined by heating in a high frequency heating furnace to obtain boron carbide.
