50weight% mullite powder having an average particle size of about 1um was dispersed in water to make a suspension, and then poured into a gypsum mold to prepare a green body. (1) When you want to prepare a sintered mullite body by using the solid state reaction of two powders instead of 1Kg mullite powder, calculate how many g each of the two powders should be mixed. (Atomic weights of Al, Si, and O are 27.0, 28.1, and 16.0, respectively) (2) The solution escapes through the plaster above and a green body is made in the shape of the plaster frame. If the pore size of the gypsum is 1um, calculate the pressure at which the gypsum sucks the solution. However, assume that the wetting angle is 0 and the surface tension value is 72 x 10^-3 N/m. 50weight% mullite powder having an average particle size of about 1um was dispersed in water to make a suspension, and then poured into a gypsum mold to prepare a green body.
