Elektroolid

Elektroolid is a high-performance dielectric ceramic material designed for electrical insulation and energy-storage components. It is characterized by high dielectric strength, low dielectric loss, and broad thermal stability, enabling reliable operation in demanding electrical environments.

The Elektroolid family includes several ceramic compositions based on aluminosilicate and zirconia matrices, doped with transition-metal oxides and rare-earth oxides to tailor dielectric properties and mechanical strength. Sintered densities typically range from 5.6 to 6.0 g/cm3, with microstructures optimized for uniform grain growth. Dielectric constants and breakdown voltages vary among variants, with loss tangents generally below 0.01 at room temperature for high-quality grades and stable performance over a wide temperature range.

Production proceeds via conventional solid-state processing: mixing oxide precursors, calcination to form a homogeneous phase, milling, pressing into shapes, and high-temperature sintering in controlled atmospheres. Additives such as magnesia or silica can adjust grain size and suppress cracking. Post-sintering machining and surface finishing enable integration into modules and substrates.

Applications include high-voltage insulators, surge arresters, ceramic capacitors, and power-electronic substrates. Due to its combination of strength, thermal stability, and dielectric performance, Elektroolid serves where compact, robust ceramic dielectrics are required.

Historically, Elektroolid emerged from collaborative research programs in Europe during the late 20th century as part of advances in ceramic dielectrics. It has since been industrialized by several specialty ceramic producers and adopted in niche high-voltage and power-electronics markets.

Safety and environmental considerations align with other ceramic oxides: the material is largely inert, though ceramic powders pose inhalation risks during handling. Standard industrial hygiene and waste-management practices apply. No unique environmental hazards have been identified for typical end-of-life processing.
