Mass Fraction Formula:
From: | To: |
Definition: The mass fraction of crystalline components is the fraction of total mass of that crystalline component from the total mass of specimen present in a polymer.
Purpose: This calculation helps in understanding the composition and properties of semi-crystalline polymers.
The calculator uses the formula:
Where:
Explanation: The formula calculates the ratio of the mass of crystalline components to the total mass of the specimen.
Details: Knowing the mass fraction helps in determining material properties like strength, melting point, and transparency in polymers.
Tips: Enter the density and volume values for both crystalline components and the specimen. All values must be > 0.
Q1: What's a typical density for crystalline components?
A: This varies by material but typically ranges between 500-1500 kg/m³ for most polymer crystalline phases.
Q2: How do I measure the volume of crystalline components?
A: This is typically determined through X-ray diffraction or other crystallographic techniques.
Q3: What affects the mass fraction in polymers?
A: Processing conditions, cooling rates, and polymer composition all influence crystallinity.
Q4: Can this be used for non-polymeric materials?
A: Yes, the formula applies to any multi-phase material containing crystalline components.
Q5: How accurate is this calculation?
A: Accuracy depends on precise measurement of densities and volumes.
