Abstract

"CERáMICA, E, VELA DE IGNIçãO". Uma cerâmica inclui alumina, em uma quantidade entre cerca de 90 e cerca de 99% em peso, um composto contendo zircónio, em uma quantidade entre cerca de 0 e cerca de 1% em peso e uma mistura de óxido, em uma quantidade entre cerca de 1 e cerca de 10% em peso. A mistura de óxido incluindo um formador de vidro e um modificador de retícula, em que a relação molar do formador de vidro para o modificador de retícula varia entre cerca de 0,8:1 e 1,2:1. O isolante cerâmico é particularmente adaptado para uso como um isolante em uma vela de ignição, para prover melhorada resistência dielétrica e resistência em derivação de mais do que 1000 megaohms a 538<198>C, a fim de reduzir a derivação da vela de ignição e, desse modo, melhorar a qualidade da centelha gerada pela vela de ignição.
