Green laser pointer can be divided into various types by shape

When grinding to weigh the drugs in the agate mortar, creamy white powder. , Slightly yellow, light green powder obtained after the first sintering, the sintering of solid surface color is uneven, which is due to density differences caused by the uneven surface of V2O5 play again grinding the sintered color of the surface is uniform . . Second for different X value of the solid sintered powder shades of color vary. X = 1, the color is yellow, the color of other drugs with the X value increases color gradually deepened. Are two ways the synthesis of polycrystalline materials characterization. Infrared spectroscopy. The experimental steps: synthesis YVO4 and CaxLa1 of-x (VO4) 2 polycrystalline powder grinding. One of the most important things for the customer should know is mastering some basic knowledge of the classification ofgreen laser pointer.
Using P-983G-type Fourier transform infrared and Raman spectroscopy, infrared spectroscopy. Investigated relatively YVO4 and CaxLa1-x (VO4) the chemical bonds between each atom in the 2 polycrystalline samples. Test Results and discussion: take the liquid phase synthesis YVO4 and Ca2La2 of / 3 (VO4) 2 measured the infrared spectra, IR spectra of the YVO 4 of Schedule 1 shows 815.35nm VO4-3 VO vibration peak, while the at 452.71nm at the peak of the characteristic peaks of rare earth ions and 1644.95nm may 815.35nm multiplier peak. It can be seen from Figure 2 803.12nm VO4-3 VO vibration peak. Here will introduce some basic knowledge of classification ofgreen laser pointer.
It can be seen from the figure here the peak is relatively wide, it may contain no complete response VO3- 418.85nm for the characteristic peaks of the La rare earth ions. Experimental steps: take the synthesis of YVO4 polycrystalline powder obtained and tested in the polycrystalline diffraction X-ray powder diffraction pattern. Sample diffraction patterns with the YVO4 standard X-ray powder diffraction pattern, whether the observed between the two diffraction peak position and strength. Take the synthesis proceeds CaxLa1-x (VO4) 2 polycrystalline powder and doped with different concentrations of La3 + CaxLa1-x (VO4) 2 powder raw materials, test in the polycrystalline diffraction X-ray powder diffraction pattern. Comparison of sample diffraction pattern CaxLa1 of-x (VO4) 2 Standard X-ray powder diffraction pattern. The classification of green laser pointer can be performed as per different classification standards.
Observed between the two diffraction peak position and strength whether the polycrystalline powder materials synthesized by the judge whether the case of a single species phase, incorporation of La3 + ions affect the phase. 2 Results and discussion: the standard XRD diffraction patterns of YVO 4: XRD diffraction pattern of the experimental process in the synthesis of YVO4: the purity of Ca3 (VO4) 2 X-ray powder diffraction standard spectrum (3) analysis of 1, the experimental steps: Weigh the synthesis of YVO4 and Ca3 (VO4) 2 polycrystalline samples of 1 g, prepared a constant volume of concentrated nitric acid dissolved into 100mL solution. WFX-110 atomic absorption spectrophotometer (Beijing Optical Instrument Factory) test samples of Fe content, analysis of its purity. For example, green laser pointer can be divided into various types by shape, by function, by material or by surface treatment and so on.
Results and discussion: can be drawn from Schedule 1 of Fe3 + of the curve as shown below: 3 + Schedule 1 shows the YVO4 in the Fe 3 + concentration 0.91ug/ml 1g YVO 4 containing Fe 3 + 9.1ug Ca3 (VO4) 2 Fe3 + concentrations for 1.21ug/ml 1g Ca3 (VO4) 2 containing Fe3 + 12.1ug. Samples containing Fe3 + in the rare earth metals and chemical properties are very similar, so the raw mineral Communist China. So will be introduced to the sample of Fe3 + into the rare earth ions in the extraction process. So the instrument cleaning process in order to reduce the error of this step can not be a test tube brush to avoid the introduction of Fe3 +, use deionized water to clean. Dividegreen laser pointer according to the shape of the laser pointer.
