Agglomerate composition
A talc agglomerate composition may include agglomerated talc particles and an agglomerization agent, and may have a conductivity of from about 1 to about 50 μS/cm. A method for making a talc agglomerate composition may include agglomerating talc particles by combining a talc feed material including talc particles and an agglomerization agent to form a talc agglomerate composition. The talc agglomerate composition may have a d 10 greater than a d 10 of the talc feed material including talc particles. A talc composition may include talc particles having a conductivity greater than 8.1 μS/cm and a viscosity in oil of less than 140 KU.
