High Compression Strength Glazed Alumina Ceramic Parts For Electrical Insulation
Compared to traditional steels, plastics, or other non-ferrous materials, modern technical ceramics provide extraordinary material qualities and features. Ceramics often have high hardness, wear resistance, compression strength, electrical resistance, and little sensitivity to acids or caustics.
Aluminum oxide ceramic is a most widely accessible technical ceramic. When a designer is contemplating ceramics as a substitute for current metal applications or if the environment inhibits metals owing to excessive temperature, electrical, chemical, or critical wear, aluminum oxide, often known as Alumina, should be the first ceramic to consider.
Many technical ceramics are made by pressing powders or pastes into rough forms and burning them at low temperatures to create delicate “green” ceramics, such as alumina or zirconia. Before the final high-temperature firing yields the solid product, a green ceramic can be machined to add holes, flats, or other characteristics.
However, high-temperature firing results in substantial shrinkage, which makes it impossible to ensure tolerances better than a few percent of the specified dimension, even with meticulous algorithms.
The cost of the material in its as-fired state is not excessive, but if precise tolerances are required, diamond grinding and polishing are needed, which can significantly increase the cost and make the individual component more expensive than a metal part. If users do not require such precise tolerances, they can save a considerable amount of money.
When developing a new application for ceramics, it is advisable to consult with material experts early to determine which features can be easily attained and which would be constrictive. The designer’s guide can be used as a resource for designers to learn more about the qualities of common ceramics.
