Abstract
The present invention relates to a method of providing product consistency of a particulate material or the product containing the same, by measuring and/or analyzing at least one interfacial potential property value of the particulate material. The method may be used as a QA/QC method to insure product consistency.
Claims22
A method of providing product consistency for a particulate material comprising the steps of:
- a) determining and maintaining at least one morphological value of a particulate material within a first target range and
- b) maintaining at least one interfacial potential property value of the particulate material within a second target range, comprising:
- i) determining at least one interfacial property value of the particulate material;
- and
- ii) adjusting at least one process variable of a process for producing the particulate material, wherein the adjustment maintains the interfacial potential property value within the second target range, wherein said particulate material is a carbon black or silica, and wherein said particulate material has said morphological value and said interfacial potential property value.
