Synonyms
A method for finding what a mineral or crystal is by using X-rays on a crushed sample
A method for identifying minerals by using X-rays on a small powdered sample to make a pattern

Morphology
The noun phrase is compositionally clear: 'powder' + 'technique' signals a method that involves powder, so a B1 learner who knows both words can infer it refers to a technique using powdered material. However, the specific technical sense (X‑ray diffraction analysis of powdered samples for mineral identification) is specialized domain knowledge and not predictable from the constituents alone, so full comprehension would likely require prior exposure.
Etymology
Powder technique comes from the simple image of crushing a mineral into a fine powder and then shining X-rays on that powder to make a pattern. The many tiny pieces point in different directions and create a clear pattern that helps scientists 'identify' the mineral, so the technique is named after the powder.
