which materials are not dissolved by liquid Si?

hi all, melting temperature of Si is 1688 K, and is said to dissolve almost all materials in liquid form. Are there any metals, maybe their oxides or other materials with
melting temperature over 1688 K that are NOT dissolved by liquid Si?
Thank you in advance, D.

AFAIK fused-quartz crucibles are used to keep molten silicon in Czochralski's method.

I am not an expert in chemistry of high temperatures.
But if there were not any, it would be very difficult to prepare silicon monocrystals of required semiconductor quality.
