Abstract :

Due to its high compressive strength, reasonable price and easy access, silicon carbide is one of the most widely used ceramics, especially in the manufacture of armor. However, high brittleness is one of the most important problems of these ceramics, which can be controlled by adding additives or modifying and improving the manufacturing process. In this paper, the method of manufacturing and processing silicon carbide ceramics has been investigated with the aim of improving properties through lines such as press pressure, humidity and grinding time. The work steps include; determining the experiment strategy, manufacturing the sample and determining the physical and mechanical properties and the best condition according to the response variables including raw density, bending and compressive strength. Finally, after manufacturing samples with different amounts of press pressure from 30 to 120 bar, grinding time from 1 to 3 hours and moisture percentage from 4 to 13% and determining their density, bending and compressive strength, the improved values of mechanical properties and The density was obtained at 7% humidity, 1 hour milling time, and 120 times press pressure. After these steps and using the determined working conditions, the main sample is finished and baked at 2000 degrees Celsius. By determining the mechanical properties including hardness, Young's modulus, fracture toughness and also the density of the final sample after baking, it is determined that the sample made with the working conditions of humidity, pressing pressure and grinding time is the most consistent with the nominal properties of the silicon carbide.
