A hydrogen torch comprising concentric inner and outer fluid delivery tubes, wherein;

Hydrogen torch

A hydrogen torch comprising concentric inner and outer fluid delivery tubes wherein the outer tube comprises silica and the inner tube comprises silicon carbide. One end of the inner tube is connected to a third tube comprised of silica which has an inlet in fluid connection with a hydrogen supply line. The outer tube is in fluid connection with an oxygen supply line. A reverse ball joint connection is used to join the tubes and defines an annulus between the inner and outer tubes through which the oxygen can flow and be isolated from the hydrogen flowing within the inner tube.

Components for semiconductor diffusion furnaces are constructed of a high purity impervious silicon carbide or silicon nitride matrix deposited on a pre-shaped fibrous matrix of silicon carbide, carbon, or carbon coated silicon carbide. The high purity of the matrix prevents undesired gaseous components from contaminating the atmosphere of the furnace, and the fibrous re-enforcement provides strength combined with light weight.

High purity diffusion furnace components

A diffusion furnace component system is disclosed which includes a liner, process tube, paddle and boat. These various elements are made up of a matrix of sintered silicon carbide which has been infiltrated with 5 to 30% by weight of silicon metal and finally coated with an impervious film or layer of a high purity refractory material such as e.g. silicon carbide.

A hollow lavatory setter (10, 10', 10', 10'') of recrystallized silicon carbide has a continuous wall of predetermined cross sectional size and shape including an outer wall portion (14, 14', 14', 14'') spaced from a bowl engaging inner wall portion (16, 16', 16', 16'') adjoining, extending around and defining the general configuration of a bowl receiving opening (18, 18', 18', 18'') and the peripheral mounting rim portion (R', R'') including a continuous mounting under surface of a rimless lavatory (L', L''). Spaced upper (24, 24', 24', 24'') and lower (26, 26', 26', 26'') wall portions extend between the inner and outer wall portions and of which the upper wall (24, 24', 24', 24'') surface is adapted to supportingly engage and maintain the continuous mounting under surface of the peripheral mounting rim portion (R, R'') in a single plane during firing in a kiln and suitable for mounting on a counter top thereafter.

Lavatory setter

A stable lightweight low mass recrystallized silicon carbide kiln furniture module (M&M') adapted for mounting on a kiln car (C, C') has a plurality of triangularly arranged post support blocks (20, 20') and hollow one piece vertical posts (30, 30', 30', 32, 32') inserted therein. The posts are provided with vertically spaced ledges (30a, 32a) or hollow pins (30a', 32a') or notches 30a' supporting refractory batts (34, 34', 34') and hollow end caps (36, 38, 36') with tie pins (36a, 38a, 36a') insertable into upper open ends thereof. Thin overlapping tie plates (40, 40') each with triangularly arranged holes interconnect with and tie the tie pins, (36a, 38a, 36a') end caps (36, 38, 36') and posts (30, 30', 30', 32, 32') together and a hollow tie bar (42, 42') interconnects with and ties the posts (32, 32') and overlapping inner portions of the tie plates (40, 40') together.
