Mark；The high-temperature conductivity for understanding associated glass is the premise for designing electric boosting kiln.
With the progress of glass cause, some performances, formula and simple glass have the need of the special glass of greatest differences
Ask increasing, such as：TFT-LCD glass substrates, but the high-temperature conductivity of this P series glass does not have related data also, institute
Positive impetus will be played for the further research and production of glass material with the measurement device of glass high-temperature conductivity.
Utility model content
The purpose of this utility model is to provide a kind of measurement devices of glassy solids high-temperature conductivity, which can be right
Glass in the solid state each temperature when conductivity be measured, it is simple in structure, easy to use.
Technical solution is used by the utility model solves its technical problem：
A kind of measurement device of glassy solids high-temperature conductivity occurs including Muffle furnace, direct current galvanometer and DC voltage
Device, muffle furnace hearth is interior to be equipped with corundum porcelain boat, and corundum porcelain boat both ends are respectively equipped with platinum piece, are placed in corundum porcelain boat to be determined
Glass, glass are in cuboid, and glass both ends are corresponding with platinum piece to be in contact, and the height of glass is less than the height of platinum piece；Muffle
Stove is used to heat glass to be determined and glass is made to maintain solid state, DC voltage generator, direct current galvanometer, platinum piece
It is in series with glass to be determined by platinum wire and forms circuit.
The beneficial effects of the utility model are that the glass in corundum porcelain boat is heated by Muffle furnace, at the same time,
DC voltage generator output voltage, direct current galvanometer are detected to flow through the electric current of glass, then can be calculated in the temperature
The resistance value of lower glass can calculate the conductivity of glass at such a temperature further according to the size of glass；Change Muffle furnace
Furnace temperature, you can measure at various temperatures, conductivity of the glass in solid state；It is simple in structure, it is easy to use.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the close-up schematic view of Fig. 1.
Specific embodiment
With reference to shown in Fig. 1 and Fig. 2, the utility model provides a kind of measurement device of glassy solids high-temperature conductivity, including
Muffle furnace 1, direct current galvanometer 2 and DC voltage generator 3,1 burner hearth of Muffle furnace is interior to be equipped with corundum porcelain boat 4,4 both ends of corundum porcelain boat
It being respectively equipped with platinum piece 5, places glass 6 to be determined in corundum porcelain boat 4, glass 6 is in cuboid, and 6 both ends of glass coat 0.5~
The conducting resinl of 1.0mm is corresponding with platinum piece 5 to be in contact, and the height of glass is less than the height of platinum piece；DC voltage generator
3rd, direct current galvanometer 2, platinum piece 5 are in series with glass 6 to be determined by platinum wire 7 forms circuit.
During measure, control Muffle furnace 1 heats up, and the temperature of Muffle furnace 1 is always in glass melting point hereinafter, measuring glass
It is solid state always in journey.The present embodiment makes Muffle furnace 1 be warming up to 600 DEG C with the heating rate of 3 DEG C/min, then adjusts straight
3 output voltage U of voltage generator is flowed, direct current galvanometer 2 is detected to flow through the corresponding electric current I of glass, be calculated at such a temperature
Resistance R=U/I of glass can acquire one group of data every 5s, read 2~4 groups of voltages and corresponding electric current at this temperature, so
The resistance of calculating is averaged afterwards.The resistance value of platinum piece and platinum wire is far smaller than the electricity of glassy solids at this temperature
Resistance value can be neglected.
In this way, you can obtain the conductivity of glass at various temperatures.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation；Any those skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
