Black Silicon Carbide Abrasives Material

Take about 10g of a representative silicon carbide sample, place it in an oven at 102℃, bake for half an hour, take it out and place it in a dryer to cool for later use. Immerse the platinum dish in a beaker of distilled water, boil it in a low-temperature furnace for 10-20 minutes, then dry it in an oven, take it out and put it in a desiccator to cool for later use. On a 10,000-degree electronic balance, accurately weigh 1 g of sample (Note: the electronic balance must be calibrated with weights before use). First, moisten the sample in the platinum dish with a small amount of distilled water, then add 4 drops of sulfuric acid, 9 drops of nitric acid, and 10 ml of hydrofluoric acid, and place it in an electric sand bath to evaporate until the white smoke of sulfur trioxide disappears. Remove it and cool it down slightly. Add 10 ml of hydrogen acid and evaporate to dryness on an electric sand bath.

Clean the outer wall of the platinum dish, pick up the platinum dish with tweezers, place it in a 1:1 warm hydrochloric acid solution, soak for 15-20 minutes, roll the platinum dish with a glass rod to pour all the materials into the beaker, rinse it with distilled water, and do not let the materials lose. Fold the filter paper, stick it on the wall of the funnel, press the multi-layer side with your thumb, and keep moistening it with distilled water so that there is no air between the paper and the wall. Let the liquid in the beaker flow along the glass rod to the filter paper multi-layer for filtration. Collect the filtrate and washing liquid in a 250ml volumetric flask, dilute to the scale after cooling, shake well, and save it for ferric oxide. Put the filter paper and silicon carbide in the platinum dish, and then place it in a muffle furnace at a temperature of 750℃ and burn it for 40 minutes. Weigh the platinum dish that has been cooled and dried to room temperature, and finally record the data.
