ちりと化すぞ - What is the function of particle と?


Could someone explain to me the function of the particle と in this case?

> ちりと化すぞ

ありがとうございます。




「と」in this case marks what the subject is turning or changing into. For
example,「死体は塵{ちり} **と** 化した」would mean "the body turned to dust".

It is similar to particle に in this use, and in fact could be replaced by に.
You can find an explanation of the difference between the two
