Specifications of 99% Alumina Electric Ceramics

99% alumina electric ceramics are advanced materials commonly utilized in electronics and industrial applications. These porcelains contain 99% aluminum oxide (Al2O3) with small amounts of ingredients to enhance efficiency. The high purity guarantees excellent electric insulation and thermal stability. This material functions well in severe settings because of its resistance to warmth and rust.

The density of 99% alumina porcelains ranges from 3.7 to 3.9 g/cm FIVE. High density contributes to mechanical strength and wear resistance. The flexural stamina generally goes beyond 300 MPa, making it appropriate for high-stress applications. Solidity degrees reach 80-90 HRA, comparable to hardened steel. This longevity reduces material wear in time.

Thermal conductivity is a vital function. These ceramics conduct warm effectively, with values around 30 W/m · K. This residential or commercial property helps dissipate heat in electronic components, avoiding getting too hot. The thermal development coefficient matches metals like molybdenum or tungsten, allowing reputable sealing in crossbreed circuits. Operating temperature levels can get to 1600 ° C without architectural failing.

Electric insulation performance is phenomenal. Quantity resistivity surpasses 10 ¹⁴ Ω · cm at area temperature level. Also at high temperatures, resistivity stays above 10 ¹¹ Ω · centimeters. Dielectric stamina remains over 10 kV/mm, guaranteeing safety in high-voltage systems. Reduced dielectric loss at high regularities makes it optimal for RF and microwave applications.

Chemical stability is an additional advantage. 99% alumina porcelains resist acids, alkalis, and molten metals. This resistance prolongs their life-span in harsh chemical atmospheres. They also show very little dampness absorption, preserving efficiency in moist problems.

These porcelains are utilized in substratums for digital circuits, shielding real estates for sensing units, and elements in laser systems. They serve as crucibles in steel melting and cutting tools for accuracy machining. The mix of electric, thermal, and mechanical residential properties makes them functional across markets.

Surface area coating options consist of polished, ground, or layered coatings to meet details requirements. Custom shapes and sizes are achievable with accuracy machining or shot molding. Compatibility with thin-film and thick-film metallization procedures allows combination into complex electronic assemblies.
