A technical object of the present invention is to devise a supporting glass substrate suitable for supporting a substrate to be processed to be subjected to high-density wiring and a method of manufacturing the supporting glass substrate, to thereby contribute to an increase in density of a semiconductor package. The supporting glass substrate of the present invention has a thermal shrinkage ratio of 20 ppm or less when a temperature of the supporting glass substrate is increased from room temperature to 400° C. at a rate of 5° C./minute, kept at 400° C. for 5 hours, and decrease to room temperature at a rate of 5° C./minute.

A method and device for the continuous heat treatment of pharmaceutical glass containers are provided. The method includes continuously conveying glass containers from an entry region to an exit region via a conveying installation having a separating plate made from an electrically conductive material, the separating plate being positioned above and/or below the conveying installation; heating the glass containers to a maximum temperature in a heating zone after passing the entry region; cooling the glass containers in a first cooling zone after passing the heating zone and before passing the exit region at a first cooling rate, wherein the separating plate separates the glass containers from heating installations in the heating zone and/or temperature changing installations in the first cooling zone; and controlling the heating installations and/or the temperature changing installations to inductively heat the separating plate in the heating zone and/or the first cooling zone.

A system and method for fire-polishing glass containers includes at least one fixed structure positioned on each side of a conveyor belt, in the forward movement direction of the glass containers; a structure that can move via each of the fixed structures, which moves with a forward movement in relation to the forward movement line of the conveyor belt, and with a backward movement in relation to the forward movement of the conveyor belt; a series of burners coupled to each of the moveable structures; sensors positioned on one side of the conveyor belt to determine the speed of the carrier belt and the distance or separation between containers; and a control device connected to the sensors and moveable structure, for adjusting and synchronizing the speed and distance of the containers.

Methods for forming a unitized crucible assembly for holding a melt of silicon for forming a silicon ingot are disclosed. In some embodiments, the methods involve a porous crucible mold having a channel network with a bottom channel, an outer sidewall channel that extends from the bottom channel, and a central weir channel that extends from the bottom channel. A slip slurry may be added to the channel network and the liquid carrier of the slip slurry may be drawn into the mold. The resulting green body may be sintered to form the crucible assembly.

A method for thermally treating an annular region of an inner surface of a glass container produced from a borosilicate glass tube is provided.
