Thermal conductivities of fused and crystalline quartz
Open accessAbstract
The thermal conductivities of fused quartz and of crystalline quartz (heat-flow at 90° to the optic axis) have been measured by steady-state plate methods; the former over the range -150 to 50° C, and the latter at 28° C. The most probable thermal conductivity values of these two materials have been formulated as functions of temperature, having in mind their use as calibration specimens for apparatus measuring the thermal conductivities of rocks, important in the calculation of terrestrial heat-flow. Detailed description is given of apparatus and measurement methods, and the results of other observers are listed and briefly discussed.

The 3ω method covers a wide range of temperature bridging the gap between low-temperature methods and elaborate means used to reduce radiation errors near room temperature and above.
“The solid circles in Fig. 7 demonstrate the wide range of temperature covered by the 3ω method bridging the gap between low-temperature methods² and the elaborate means23–25 used to reduce radiation errors near room temperature and above.”
From Thermal conductivity measurement from 30 to 750 K: the 3ω method (1990) · cites this paper as [23]
The Present Measurements section (page unavailable) describes a guard heater and insulation that reduced heat losses in measurements near 28°C, supporting the citation’s reference to measures used near room temperature. Our copy does not identify those losses as radiation errors or discuss the 3ω method; the latter is the citing authors’ own comparison, not a finding attributed to Ratcliffe. (LLM, conf=0.80)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
