Are you referring to soda ash or briquettes, exactly? If you’re referring to soda ash, then based on the data you provided, it’s impossible to determine whether it’s light ash or heavy ash ； If it’s briquettes, I’m not aware of the standards. I hope the OP can clarify this a bit.
It’s soda ash. Foreign suppliers provide only this much data. Can we tell whether it’s light or heavy from this?
As far as I know, soda ash always comes in granular form; I’ve never seen it in a square shape. Unless it has clumped together or been deliberately shaped that way, it won’t have such a regular shape. Moreover, there are no coal-type or the size indicators you mentioned in soda ash either. Your metrics were translated from a foreign language, right?
Generally, the distinction between light and heavy ash is made based on the bulk specific gravity. In most cases, it’s possible to distinguish between light and dark gray with the naked eye.
Okay, let me ask about the specific parameters
Okay, please be a bit more detailed and precise in your question.
It’s heavy ash. 15 ÷ (0.4 × 0.25 × 0.13) = 1158 grams per liter = 1158 kg per cubic meter.
If calculated according to your interpretation, it should be heavy ash.
He wants it to be compressed into blocks: 15 g per block (maximum). Dimensions: 40×25×13 mm (maximum). Is there any pure soda ash available in this block form???
This is the first time I’ve heard that soda ash is sold in brick form. If what you said is correct, then Piao’er’s explanation is right.
