Furnace of single crystal of 2 inches of carborundum is in Shandong university d
From;    Author:Stand originally

As we have learned, from 2007 the bottom begins, through half an year much time tackles key problem difficultly, compositive innovation, key laboratory of state of material of Shandong university crystal develops a heat of single crystal of 2 inches of carborundum successfully, grow gave single crystal of 2 inches of carborundum.

This lab is own the carborundum single crystal of research and development grows highest temperature can amount to furnace 2500 ℃ , vacuum leakage rate is minor, actuating pressure can accuse limits wide, grow parameter automata, grow furnace runs stability, repeatability of grown junction fruit and stability are tall, development cost grows to import single crystal only the 1/3 of furnace, dimensions changes the cost that equipment makes to still can drop further, sweep besides the crucial obstacle in process of industrialization of carborundum single crystal, laid good foundation for carborundum industrialization.

In recent years, I what give priority to body with semiconductor illume saved photoelectron industry to obtain rapid development. Before this, the single crystal of big diameter carborundum that our country can make semiconductor illume raw material grows furnace counts an import all the time, semiconductor illuminative produces cost house not to fall high.

This the success of furnace of carborundum single crystal is developed, the mark is worn the last difficulty of carborundum industrialization by breach, for Shandong the province walked along the semiconductor illumination that has Shandong distinguishing feature to lay solid foundation, also grow implementation of help our country from single crystal at the same time furnace is made, single crystal grows, what underlay processes application is all and homebred change.

In recent years, the Shandong that gives priority to body with semiconductor illume saved photoelectron industry to obtain rapid development, but the single crystal of big diameter carborundum that can make semiconductor illume raw material grows furnace counts an import all the time however, cause semiconductor illuminative to produce cost house not to fall high. Key laboratory of state of material of Shandong university crystal has old single crystal to grow with experience of semiconductor material research and development. By 2007, they begin to have the development of furnace of carborundum single crystal. Below the guidance of Jiang Minhua academician, scholar of the Yangtse River hires professor Dr. Xu Xiangang to guide the member that the task is comprised especially, those who pass much time of half an year is difficult tackle key problem, completed a part treatment and purchase, the installation that controls development of circuit, software and single crystal furnace is debugged, undertook single crystal grow experiment. Put forward single crystal to rotate with promote falling innovation plan, finished vacuum design, high pure safeguard of aeriform transport, cooling water and plan of electric source control, improved the defect that imports single crystal furnace, successfully development goes heat of single crystal of 2 inches of carborundum, grow gave single crystal of 2 inches of carborundum.
