| Abstract: | Fused quartz as refractory for shell-making was widely used in the United States.Fused quartz has features of low density,thermal expansion rate,good permeability and high creep resistance as well as easy mold-filling and shell-releasing.The merits and demerits of fused quartz and ZrO_2 as refractory were compared.It was found that the fused quartz exists in reality and imminence for application in the investment industry due to its advantages of price and properties. |
