| This information is disclosed a method for preparing a quartz precision casting casting powder, which is a mixture of quartz powder with a powder mixture of high temperature quartz, solid binder uniform composition, temperature stabilizers can also be added when used according to the situation, defoamers coagulant. It provides precision casting casting quartz powder production costs low, easy to use, wide application, they prepared shell with good mechanical strength and excellent copy of, no crack, no distortion, non-stick sand, collapsing good, casting out of the casting surface is smooth, high dimensional accuracy, casting the passing rate is also very high.
