Embodiment 1

[0029] Step 1: Basic treatment of related equipment: Clean the inside and outside of the quartz tube with distilled water. After cleaning, dry it, and then use hydrofluoric acid to quickly clean the quartz tube to completely clean the silica powder on the surface of the quartz tube. Then use distilled water to clean the quartz tube while soaking. After the comprehensive cleaning is completed, wipe the inner and outer surfaces of the quartz tube clean, and then fully rotate and dry;

[0030] Step 2: Basic operation of the quartz tube: put the quartz tube in a helium-protected environment, then load arsenic particles into the quartz tube, then use a vacuum machine to vacuum the quartz tube, and then seal the quartz tube;

[0031] Step 3: Initial processing of arsenic particles: place the quartz tube loaded with arsenic particles in a sealed high-temperature and high-pressure furnace, raise the temperature in the furnace to 700 degrees Celsius, the arsenic particles are initially ...

Abstract

The invention discloses a manufacturing method of an arsenic rod for molecular beam epitaxy. The manufacturing method specifically comprises the following steps: step 1, basic treatment of related equipment; step 2, basic operation of a quartz tube; step 3, primary processing of arsenic particles; step 4, high-order processing of the arsenic particles; step 5, secondary melting of the arsenic particles; and step 6, basic forming of the arsenic particles. The invention relates to the technical field of arsenic rods. According to the manufacturing method of the arsenic rod for molecular beam epitaxy, the arsenic particles can be primarily melted through high-order processing and then are thoroughly melted in a high-temperature high-pressure furnace through secondary melting, so the arsenic particles can be smoothly formed subsequently, poor forming effect caused by incomplete melting of the arsenic particles is avoided, and the percent of pass and the product quality of later-period products are indirectly improved; and the raw material, namely the arsenic particles can directly enter a helium protection environment, so oxidation of the arsenic particles is effectively avoided, and impurities are prevented from being generated in the arsenic rod manufacturing process.

Description

technical field [0001] The invention relates to the technical field of arsenic rods, in particular to a method for manufacturing arsenic rods for molecular beam epitaxy. Background technique [0002] Arsenic is a non-metallic element. It is located in the 4th period and group VA in the periodic table of chemical elements. The atomic number is 33 and the element symbol is As. The elemental substance is in the form of gray arsenic, black arsenic and yellow arsenic. exist. Arsenic exists widely in nature, and hundreds of arsenic minerals have been discovered. Arsenic and its compounds are used in pesticides, herbicides, insecticides, and many kinds of alloys. Its compound, arsenic trioxide, is known as arsenic and is a highly toxic substance. Arsenic is used as an alloy additive to produce lead projectiles, printing alloys, brass (for condensers), battery grids, wear-resistant alloys, high-strength structural steels, and corrosion-resistant steels. Prevents dezincification ...
