Niobium is a chemical element with atomic number 41 and is represented with the symbol Nb in the Periodic Table. It is a soft, ductile transition metal which is resistant to corrosion due to the presence of an oxide layer on its surface. It is one of the most common elements found in the Earth’s Crust. It is often found in the pyrochlore mineral.Oct 12, 2023 · Thanks for contributing an answer to Chemistry Stack Exchange! Please be sure to answer the question.

Oct 1, 2017 · I have printed the model in HIPS and the support in PLA. I have put the 3D model in a ultrasonic cleaner in the solution with water and sodium hydroxide. (1 liter H2O + 200 grams NaOH) The PLA has dissolved after 3 hours with temperature 65° and 1 hour of ultrasonic sound. I attach a youtube link with a similar experiment. Effect of impurities on melting point. This is a 10th-grade question. The melting point of a substance decreases with increase in presence of impurities in it. The melting point of ice decreases from 0 °C to -22 °C on mixing salt in it in proper proportion. That is why salt is added to make freezing mixtures to keep ice creams frozen.
