1. Melemo e ikhethang ea Aluminum nitride:

Ka lebaka la boitšoaro bo botle ba eona bo tsamaisang silicon, aluminium nitride e se e le thepa e tšoenyang tšimong ea elektroniki. Aluminium nitride ke a hexagonal e nang le moea o nang le moea o fokang oa motlakase, o sa sebetseng hantle le silicon. Ha se feela boitsebiso bo nepahetseng bakeng sa ho kenya moloko o mocha oa mocheso le lisebelisoa tsa motlakase, alumium nitri e lebang evation, jj., ka tebello e sephara.

Ho latela lipatlisiso tsa "tsoelo-pele e ncha Thutong ea lintho tse susumetsang tsa ho kenella ka matla, 'me ha e amehile ka mokhoa o tšoanang ka mokhoa o tšoanang ka lebaka la ho hola Lintho tse supang tse kang Al2O3 li ameha haholo ka lebaka la boitšoaro bo tlase ba ho futhumatsa. Its value is about 1/5 of A lN ceramics and the linear expansion coefficient does not match Si, which can not meet the actual demand, refer to the figure 2.
