Process method for producing quartz tube by using solid state method

Abstract

The invention discloses a process method for producing quartz tubes by using a solid state method. The process method comprises the following steps of: (1) selecting a rare-earth element; (2) uniformly mixing a plurality of kinds of solid rare earth nitration according to the quantity of quartz melting materials inside a continuous melting furnace; (3) mixing and stirring the uniformly mixed rare earth nitration by using a turbine stirring machine; (4) adding the rare earth nitration into the continuous melting furnace directly; (5) adding the rare earth nitration into the continuous melting furnace; (6) continuously rising the temperature of the rare earth nitration and the quartz material; (7) rising the temperature of the continuous melting furnace gradually; (8) keeping the temperature inside the furnace to be black red; (9) generating the black red quartz tube and wholly coloring and shaping; and (10) continuously producing the wholly colored black red quartz tube. The process method has the advantages of simple process and low cost.
