How to Select Dihydrate, Hemihydrate and Anhydrous Whiskers

Crystal-form selection starts with temperature, moisture, matrix polarity and the finished-product target.

Define the operating boundary

Confirm matrix grade, process, maximum temperature, moisture, current fillers and target properties. A “best dosage” has no comparable basis without these conditions.

Build a comparable trial

1. Fix raw-material batches and specimen preparation.
2. Keep a blank and set a dosage gradient.
3. Record properties, appearance, processing and unit cost.
4. Repeat the strongest candidate.

Before production

Confirm feeding, dispersion, shear, energy, cycle time and batch consistency on actual equipment.
