3.6.2.1 before rice powder particles ไปวิ analysis first phase from water to make the surface of the powder particles formed film.Oxide every time. To prevent oxidation with air, which will result in serious analysis phase.Powder particles was wrong.3.6.2.2 Na particle powder grinding finely by particle size of less than 100 micron.3.6.2.3 put powder particles into the frame, put a sample (Sample Holder).3.6.2.4 using glass powder particles in the press frame put water samples are smooth and compact.3.6.2.5 import restrictions XRD in order to analyze the structure of the voltage.A 40 kV and current 30 ma.The measurement of 3.6.2.6 during shedding swept the empty corner as 20 degrees to 120 degrees.Scanning speed of 5 degrees per minute and step scan 0.01 degrees.3.6.2.7 data was compared with data in a file JCPDS to detect the crystals.Or phase (Phase).3.6.2.8 data in the angle of reflection measurement of X-ray lines (X-Rays), from.Analysis XRD to calculate average crystal size by using the relationship of the shearer Scherrer.Equation) [] is shown 106 equation.
