摘要：
The present invention relates to a cellulosic particle body comprising interconnected cellulosic small particles with small interparticle spaces and to a method of producing said cellulosic particle body which comprises dispersing cellulosic small particles in an alkaline medium and contacting the resulting suspension with a coagulating solution. In this specification, the above technology will be referred to as the first invention.
