摘要: Lightweight composite particles, primarily comprising various bentonite clays, but which may include other functional solid particles, are formed by introducing expanding gases or air into the particle forming process. The methods presented create the ability to reduce the bulk density of the composite particles while maintaining and in some cases even increasing the particle strength.
