This method causes less environ ——mental pollution than the tradi——tional method using HNO3. Some, opti-mum technical conditions have been given here. It is shorvn that traditional method for manufacturing expandable graphite with HNO3 as oxidizer can be replaced completely with H2O2 as an oxidizer. Expandable graphite made, in this way has the same characteristics as that made in traditional way, but the pollution of NO2 to air decreases greatly.展开更多
