Abstract
PURPOSE: To obtain the title extender for agricultural pesticide powder free from scattering, by calcining a raw material, e.g. pagodite, at a specific temperature, and by pulverizing to a specific particle size.
CONSTITUTION: Pagodite, alunite, or waste fire brick is calcined at about 1100°C, and pulverized by a usual roller mill to powder of an average particle size of 20W 25μ, wherein 20% or less of the totla amount has a size ≤10μ, and 95% or more has a size ≤44μ, to give an extender for DL-type powder (DL clay). The extender has a large particle size and scarcely scatters, thus causing no ervironmental pollution.
