The influence of hydrothermal conditions with alkaline solution on the particle size distribution of zeolite species P(P_1) and hydroxy sodalite (HS) from silica rich allophane (volcanic ash in southern Kyushu, Japan) was investigated. The higher the hydrothermal temperature was, the larger the particle size of both P_1 and HS became and the more broad the particle size distribution curve of both PI and HS became. Usually, the particle size of HS was larger tham that of P_1. The percentage of large particle (above 20μ) of HS was more than that of P_1. As the temperature was lowered, the large particle of HS increased, but that of P_1 decreased. By seeding, the degree of supersaturation immediately before preciptating of products was decreased and the particle size of both P_1 and HS became larger.
