The melting point of Coconut shell charcoal cannot be determined, because the substance is thermally unstable (i.e. starts to decompose) at temperatures below the melting point.The freezing point of Coconut shell charcoal cannot be determined, because the substance is a solid at ambient temperatures, and cannot be melted without decomposition.Coconut shell charcoal is manufactured at temperatures around 500°C, so it does not melt at a temperature below 300°C.
When coconut shell charcoal
is heated, it starts to decompose without melting. This is a
characteristic of all charring materials.
The decomposition is used to
characterize coconut shell charcoal in the ‘volatiles’ determination.
Typically 10% of weight is lost (not including the weight loss by
drying) when the substance is heated to 900°C. After such a test, the
material retains it original shape (e.g. chunk or powder) and does
therefore not melt during the test.
The freezing point of the
substance cannot be determined, as the substance cannot be converted
into the liquid state first without decomposition.
shell charcoal is manufactured at temperatures around 500°C, so the
melting point is higher than 300°C.
