Quality enhancement via structure improvement
In ceramic productions, quality of products is normally compromised by their productivity. Production at high rate makes products vulnerable to formation of intrinsic defects as well as exposure to machinery-caused defects which lower the reliability of the product. Products with defects may counter the cost efficiency of the production process resulting in higher cost in product mending and losses. In a high production rate process such as dry-pressing, causes of defects formation must be well understood and controlled in order to harvest the optimum advantage of the process. It is essential to characterize the important parameters contributing to defects formation and recognize ways to totally diminish or at least reduced defects to the lowest level possible. Homogeneity of internal structure of ceramic body is a key point in enhancing their qualities where it can be retarded due to formation of defects. Manipulation of surrounding conditions during forming process, additives properties, and raw material properties are given into consideration in reducing defects formation within ceramic body.
