CERAMICS - THE IDEAL INSULATOR

Ceramics are the oldest and still one of the best electrical insulators because of their stability and non-conducting properties. Highly arc and track resistant, they are dimensionally stable at elevated temperatures and will not char or burn. Chemicals, weathering, and bacteria will not affect their properties or tear down their structure. Ceramics have a low power factor and dielectric constant.  Their high compressive strength and virtually no cold flow assure dimensional stability and rigidity. Ceramics also reduce eddy and induction current. A special vacuum process can produce a piece with low water absorption. Many of these characteristics make it desirable for micro-wave applications.

Ceramics are also heat resistant. They have many applications in the foundry and refractory industries because they can withstand thermal shock, even molten metal, and still maintain their rigidity.

Ceramics are economical to use. The basic ingredients are readily available from supplies within the United States. No international cartels control price or availability. This, coupled with comparatively low cost dies and molds, offers an economical and practical means to fulfill most insulation requirements.
