    coefficient because of the ball shape of ceramic sand.hen working with the core shooter, the sand is easy to go to small corners. Thus, it will get a smoother casting surface. 2. Most of the chemical content of ceramic sand is Al2O3 and SiO2. It has high anti-thermal ability up to 1800°C. There don’t exist acid or alkali in the sand. So it won’t get a reaction with resins or molten steel. Th
