Lavite material

Lavite.

The new insulating material lavite possesses several qualities which recommend it. It can be easily machined, it has great mechanical and disruptive strength, and also great ability to resist the action of chemicals or high temperatures. Its strength in cross-bending has been found to be from 6,000 to 12,000 pounds per square inch and in compression from 20,000 to 30,000 pounds per square inch. The breakdown voltages required in a series of tests with this substance as a dielectric were from 200 to 250 volts per one one-thousandth of an inch, its disruptive strength being high in comparison with other materials such as fiber, wood, asbestos, etc. Aqua regia is the only solvent which will attack lavite, and it is unaffected by temperature up to a cherry-red heat. This substance is made by the D. M. Steward Manufacturing Company of Chattangooa, Tenn.
