AEROXIDE® Alu C Silica

AEROXIDE® Alu C Silica is a fine-particulate, pure aluminium oxide with high specific surface area and marked aggregate and agglomerate structure. Because of it high purity and low water content, the product can be used well as an additive to an organic materials, for heat insulation, and also as a catalyst substrate. The positive surface charge can be used to control the electrostatic charge.
