SUBSTRATE WITH LOW-PERMEABILITY COATING FOR THE SOLIDIFICATION OF SILICON |
摘要 |
A substrate characterised in that it is at least partially surface-coated with a coating containing at least one so-called “barrier” layer having silica and one or more material(s) X selected from among SiC, Si, Si3N4, in which layer the amount of X varies between 25-wt. % and 50.-wt. % in relation to the total weight of the barrier layer, the barrier layer being formed by grains of one or more materials X covered at least partially in a silica shell, and the barrier layer being in direct contact with the substrate. |
