The purpose of using a green compact in sintering is to create a pre-formed shape that can be easily sintered into a final product. The green compact is made by pressing the powdered material into a specific shape and density, which allows for better control over the final dimensions and properties of the sintered part. Additionally, the green compact helps to minimize the amount of shrinkage and distortion that can occur during the sintering process, resulting in a more precise and uniform final product. Overall, using a green compact in sintering helps to improve the efficiency and quality of the sintering process. **
