Quartzite VS Silica VS Silicon Dioxide

    Are they the same?

    Quartzite is found in the nature as the rock form.

    The colors are, some light brown, and some transparent.

    Silicon dioxide is a powder, its color is white.

    What is a silica?

    Is there available a picture/image of a silica?

    I have a mix of rocks such as below image:


    What kind of rocks are they?

    She says it was found in the nature.

    I doubt it because the shape, like was shaped by the hand.

    It like a synthesis then shaped by the hand.

    What is the chemical composition?

    I will crush them using the stone crusher machine.

    I doubt the form will be a powder instead of more rough than a powder.

    How do I make it to be a powder?

    How many times to be crushed so that the form will be a powder?

    What equipment do I need to make it as a powder?

    Or what chemical additive to be used to make it as a powder?

    Thank you
