Abstract
The invention provides an arsenic lead alloy synthesis and sublimation integral furnace used for producing high-purity arsenic, and relates to the technical field of industrialized purification and production of a non-metallic material, and in particular relates to an arsenic lead alloy synthesis and sublimation technology used to produce the high-purity arsenic which is the base material of a semiconductor. The integral furnace is composed of a material section, a control section, a transition section and a product material tank which are communicated with each other in turn, wherein the material section, the control section and the transition section are respectively formed by a furnace body, furnace tiles and furnace wires, and an insulating layer; an aluminum oxide ceramic lead molten pool is formed in the material section, a material inlet is formed above the material section, and an air inlet is formed on the front end of the material section; and ceramic packing is arranged in the control section. According to the integral furnace provided by the invention, the airflow speed in the control section has a good controllability, the transition section is also convenient to adjust the temperature, and synthesis and sublimation can be effectively ensured to be carried out smoothly.
Description
Technical field
The present invention relates to a kind of industrialization purification production technique field of non-metallic material, particularly the production of semiconductor foundation material high purity arsenic arsenical lead synthesizing sublimation technology.
Background technology
The production method of high purity arsenic has chlorination rectification method, plumbous molten bath subliming method and hydrogen arsenide cracking process at present, and their common defects is production cost height, little in batches, can not meeting the market requirement.In addition, there is operation cost height again in the chlorination rectification method, produces, unstable product quality fragile with tower, easily produce the arsenic chloride gas leakage in the production process, there is potential safety hazard in production process; Plumbous molten bath subliming method exists the quality can not be up to standard; There is the potential safety hazard of hydrogen arsenide toxic gas leakage in the hydrogen arsenide cracking process.Application number is the defective that the production method of 2006100395410 high purity arsenic has not only overcome above three kinds of methods, also combine the advantage of plumbous molten bath method and chlorination rectifying reduction method, first formation arsenical lead has been proposed, from wherein extracting arsenic with the method for sublimation separation, the acquisition purity that more isolated arsenic distil in hydrogen is the arsenic of 7N again.But the existing equipment platform number that this method adopts is many, complex operation step, and artificial amount is big, and output is little, the cost height.
Summary of the invention
The present invention seeks to design a kind of rationally, discharging is stable, be suitable for the arsenical lead synthesizing sublimation all-in-one oven of producing high purity arsenic in batches.
The present invention mainly is made up of the material section, control section, transition section and the product material pot that are communicated with successively mutually, and described material section, control section, transition section are made up of body of heater, tile stove silk and thermal insulation layer respectively; The plumbous molten bath of aluminium sesquioxide pottery is set in described material section, above described material section, opening for feed is set, at the front end of described material section inlet mouth is set; At described control section built-in ceramic filler.
During operation, in the plumbous molten bath of aluminium sesquioxide pottery, insert lead in advance, heat up, after treating plumbous the thawing, by the opening for feed interpolation particle arsenic of material section top, at a certain temperature, arsenic material and the plumbous arsenical lead that forms, heating up distils, and this moment, the inlet mouth to the material section fed rare gas element, and distillation arsenic material is brought into the product material pot through control section and transition section.
Because the present invention adopts ceramic packing, make the interior gas velocity controllability of control section good, transition section also is convenient to regulate temperature, can effectively ensure carrying out smoothly of synthetic and distillation.The present invention is reasonable in design, discharging is stable, is suitable for to produce high purity arsenic in batches.
The present invention also sets out gas port in the upper end of product material pot, and the pipe connecting that was tightly connected in the air outlet, the other end of described pipe connecting are inserted into one and observe in the bottle.By connecting bottle is observed in air-flow introducing in the body of heater, observed the built-in water body of bottle, by whether bubbling judges whether body of heater stops up in the observation bottle.

Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention mainly is made up of the material section 1, control section 2, transition section 3 and the product material pot 4 that are communicated with successively mutually.
Material section 1, control section 2 and transition section 3 are high respectively to be provided with corresponding body of heater, is provided with tile stove silk and thermal insulation layer in each body of heater.
The plumbous molten bath 5 of aluminium sesquioxide pottery also is set in material section 1, opening for feed 6 is set above material section 1, at the front end of material section inlet mouth 7 is set.
In control section 2, also put ceramic packing 8.
Set out gas port 9 in the upper end of product material pot 4,9 pipe connectings 10 that were tightly connected in the air outlet, the other end of pipe connecting are inserted into one and observe in the bottle 11.
Claims (2)
1. be used for the arsenical lead synthesizing sublimation all-in-one oven that high purity arsenic is produced, it is characterized in that mainly being made up of the material section, control section, transition section and the product material pot that are communicated with successively mutually, described material section, control section, transition section are made up of body of heater, tile stove silk and thermal insulation layer respectively; The plumbous molten bath of aluminium sesquioxide pottery is set in described material section, above described material section, opening for feed is set, at the front end of described material section inlet mouth is set; At described control section built-in ceramic filler.
2. according to the described arsenical lead synthesizing sublimation all-in-one oven for high purity arsenic production of claim 1, it is characterized in that setting out gas port in the upper end of product material pot, the pipe connecting that was tightly connected in the air outlet, the other end of described pipe connecting are inserted into one and observe in the bottle.
