Document Type and Number:
Japanese Patent JP2007534476
Kind Code:
A
Abstract:
The invention relates to a method for dispersing and passivating particulate powders in water and aqueous media. It is particularly advantageously applicable in the handling and processing of non-oxidic powders, e.g., in the ceramic and hard-metal industry. In the method claimed auxiliaries are added due to the process. According to the invention this method is characterized in that polyvinylamines and/or the initial products thereof are used as these auxiliaries.
