Development of aphanitic graphite purification
摘要
Abstract
Graphite,an important non-metallic mineral resource, has the features of high temperature resistant,high corrosion resistant,high plasticity and special conductive. It has been widely used in chemical,metallurgical,nuclear power,aerospace and defense industries. With the growing applications of graphite,the requirements for high purity of graphite are also increasing. Meanwhile, more and more attention also has been paid to the aphanitic graphite purification. Various methods for graphite purification are described in detail,including flotation, alkali-acid processing method, hydrofluoric acid washing,chloridizing roasting and high temperature purification. The basic principles,research progresses,practical applications,and the advantages and disadvantages of various method are explained systematically. Some key points in aphanitic graphite purification, such as efficiency,energy saving,consumption,and green environmental protection,are put forward. The development directions of aphanitic graphite purification,including the selection of environmental friendly,high-efficient,energy-saving equipment and the application of wet-fire joint technology,are also pointed out.关键词
