Assertion: basic magnesium carbonate | /r/HasAspect | high mechanical strength
Facets:
Source sentences:
text: It has been heretofore attempted to manufacture heat insulating materials containing at least 85% basic magnesium carbonate having a high mechanical strength to the desired degree by low pressure molding, but such attempts have met with little success due to the fact that the magnesium carbonate, as now produced does not possess the requisite physical properties.
