Wet ball milling of zeolite HY

Powder Technology, 2004
Abstract Wet ball milling, as a potential means to decrease the particle size of zeolite HY with minimal loss of crystallinity, was investigated. The diameter of the ball as well as the milling speed and time were varied in the experiments. Particle size distributions of the commercial zeolite HY and the ground samples were obtained to determine the ...
