摘要： PURPOSE:To make it possible to obtain a stubborn holding structure to a cathode chip by sintering integrally a cathode chip of a hexaboride and a holder piece of a high melting point metal with a paste including a colloidal carbon and a high melting point metal powder. CONSTITUTION:This cathode is made to reform to hold a cathode chip 4 of a hexaboride at the center of a tungsten wire 3, and the hexaboride is a hexaboride of an alkaline earth metal or a rare earth metal, whose tip is processed into a sharp conic form to make a minute cathode chip 4. A holder piece 5 is made of a high melting point metal to hold the base of the cathode chip 4 solidly in a high temperature, used by forming into U-shape with bending parts along the opposing sides surfaces of the cathode chip 4. To sinter the cathode chip 4 and the holder piece 5 integrally, a paste including a colloidal carbon and a high melting point metal powder is used. In such a way, a stubborn holding of the cathode chip 4 is made possible, and the service life can be extended.

1 R
2 N-R
3 and R
1 R
2 N-R
3 H
+ Cl
- (wherein R

摘要： PURPOSE:To produce dichlorosilane, monosilane, etc. in large quantities, in high efficiency, by supplying the stock hydrogenated silicon chloride to a reaction column, carrying out the disproportionation reaction using a specific catalyst, and at the same time, separating the products taking advantage of the distillation effect. CONSTITUTION:A tertiary amine substituted with aliphatic hydrocarbon group of formula [R1, R2 and R3 are aliphatic hydrocarbon group (the total carbon number is >=10)] (e.g. tri-n-octylamine) is used as a catalyst. A hydrogenated silicon chloride (e.g. trichlorosilane) is introduced through the line 4 to the reaction column 1 (2 is reboiler) having the form of a distillation column, to effect the disproportionation reaction. The produced low-boiling compounds (monosilane, monochlorosilane, etc.) are collected in the reservior 7 via the column top and the condensers 3, 6, and the high-boiling compounds (silicon tetrachloride, trichlorosilane, etc.) are extracted from the column bottom, evaporated in the evaporator 9 to separate the catalyst, and collected in the reservior 12 via the condenser 11. The separated catalyst is recycled to the reaction column 1 by the pump 10.

摘要： PURPOSE: To prepare trichlorosilane at an improved reaction rate, by separating powdery materials discharged together with a trichlorosilane-containing gas formed by a fluidized bed reactor, circulating it through the reactor.
CONSTITUTION: In a method to prepare trichlorisilane by feeding one or more gases selected from (a) a mixed gas of silicon tetrachloride and hydrogen, (b) a mixed gas of silicon tetrachloride, hydrogen chloride, and hydrogen, and (c) hydrogen chloride gas to a fluideized bed reactor charged with metal silicon powder, powdery materials discharged together with a trichlorosilane-containing gas formed by the reactor is separated from trichlorosilane, and the powdery materials are circulated through the reactor. The reason why the reaction rate is extremely improved is considered that metals except silicon and their chlorides act as a catalyst, and the reaction rate is increased.
