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.

Description

technical field [0001] The invention relates to the technical field of inorganic nonmetals, in particular to a process method for producing quartz tubes by a solid state method. Background technique [0002] At present, the red quartz tube produced by doping rare earth element oxides with high-purity quartz raw material liquid method, the doped rare earth elements and the ratio are copper nitrate (0.1-5%), europium oxide (0.1-5%), magnesium oxide (0.1-5%), etc., after being diluted with a certain amount of water and acid, and then soaked with quartz raw materials, after uniform mixing of liquid rare earth elements and quartz raw materials, high-temperature drying, and gradual cooling, the quartz raw materials and Rare earth elements are evenly doped, and then put into a continuous melting furnace to produce red quartz tubes; the disadvantage is that this liquid doping method has complex processes, high production costs, and low efficiency. Contents of the invention [000...
