Definition: This calculator determines the total volume occupied by crystalline components in a specimen based on the volume fraction of crystalline components and the total specimen volume.
Purpose: It helps materials scientists and polymer researchers quantify the crystalline phase in semi-crystalline materials.
The calculator uses the formula:
Where:
Explanation: The volume fraction is multiplied by the total specimen volume to obtain the absolute volume occupied by crystalline components.
Details: Knowing the crystalline volume helps in understanding material properties like strength, transparency, and thermal resistance in polymers.
Tips: Enter the volume fraction (between 0 and 1) and total specimen volume (must be > 0). The volume fraction represents the proportion of crystalline material in the specimen.
Q1: What is a typical volume fraction for semi-crystalline polymers?
A: Common values range from 0.3 to 0.8 depending on the polymer type and processing conditions.
Q2: How is the volume fraction determined experimentally?
A: Typically measured using techniques like X-ray diffraction (XRD) or differential scanning calorimetry (DSC).
Q3: Can this be used for non-polymeric materials?
A: Yes, the formula applies to any multi-phase material where you need to calculate the volume of one phase.
Q4: What if my specimen has multiple crystalline phases?
A: The calculator gives the total crystalline volume. For individual phases, you would need their respective volume fractions.
Q5: How does temperature affect these calculations?
A: Temperature changes can alter both the volume fraction and total volume, so measurements should be at consistent temperatures.
