In summary, the conversation discusses the properties and characteristics of quartzite and silicon dioxide. It is mentioned that quartzite is found in nature in rock form and can come in various colors. Silicon dioxide, also known as silica, is a white powder. The conversation also mentions using a stone crusher machine to crush rocks into a powder form. However, it is noted that the chemical composition cannot be determined from just a photograph. It is also mentioned that the smooth shape of stones can be formed by water erosion.

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:

Stones

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

FAQ: Quartzite VS Silica VS Silicon Dioxide

1. What is the difference between quartzite, silica, and silicon dioxide?

Quartzite is a metamorphic rock made up of the mineral quartz, while silica is a compound made up of silicon and oxygen. Silicon dioxide is the chemical name for the compound that makes up both quartzite and silica.

2. Is quartzite the same as quartz?

No, quartzite is a metamorphic rock while quartz is a mineral. Quartz can be found in many other types of rocks, but quartzite is specifically composed of the mineral quartz.

3. Which is stronger, quartzite or silica?

Quartzite is generally considered to be stronger than silica. This is because the heat and pressure involved in the formation of quartzite cause the quartz grains to fuse together, creating a harder and more durable rock.

4. Can silicon dioxide be harmful to humans?

No, silicon dioxide is a naturally occurring compound and is not considered harmful to humans. In fact, it is commonly used in many products such as glass, ceramics, and even food additives.

5. Is quartzite more heat resistant than silica?

Yes, due to the fusion of quartz grains in quartzite, it is typically more heat resistant than silica. Quartzite can withstand high temperatures without melting or deforming, while silica may melt or soften under extreme heat.
