What is the reducibility of silica?

Silicon dioxide does not have typical oxidizing or reducing properties.
However, since Si has a valence of+4, which is the highest, SiO2 has oxidizing properties. O is -2 valence, which is the lowest price, so SiO2 also has reducibility. However, none of them are typical. There are very few oxidation-reduction reactions involving SiO2 in middle school. The reaction of SiO2 as an oxidant: C+SiO2==high temperature==Si+2 CO ↑ (preparation of crude silicon) The reaction of SiO2 as a reducing agent: I really haven't remembered this, but I haven't thought about it in high school.
