Electric conductor coated with an adhering insulating layer stable at high temperature

摘要

In order to cause to adhere, on an electric copper conductor, a refractory insulating layer which consists of Al2O3, SiO2 or BN and is stable at high temperatures, there is situated, between the conductor and said insulating layer, an anchoring film which consists of mineral particles finely dispersed in a matrix of electrolytically deposited copper. <IMAGE>
