Abstract

PURPOSE:To obtain a tackiness increasing agent for railway vehicles which has a greater tackiness-increasing effect than that of a sand material by using a particulate composition consisting of alumina and silica. CONSTITUTION:The tackiness increasing agent is obtained by sintering a particulate mixture consisting of 40-95wt% of alumina and 60-5wt% of silica, followed by crushing the sintered material.
