Abstract
Composite particles designed as a filler for gaskets, caulking compounds and plastics in general. The unique properties are obtained by using a soft metal core galvanically similar to the metal the sealant will be in contact with. The oxide surface of the core metal is typically breached by a multitude of small hard semiconductive or conductive particles, thus making low particle-to-particle contact resistance through the body.
Claims18
A composite particle comprising in combination:
- an electrically conductive core material having a surface oxide layer;
- and
- an electrically conductive refractory material;
- said core material and said refractory material being conductively fused.
