ABSTRACT:
Disclosed is a heat-resistant composition particularly useful to produce heat-resistant boards or tubes, capable of resisting to a high temperature for a substantial period of time. The composition comprises from 70 to 90% by weight of a fibrous-like, synthetic forsterite obtained by calcination of chrysotile asbestos fibers at a temperature of from 650.degree. C. to 1450.degree. C., the synthetic forsterite having an MgO:SiO2 ratio lower than 1:1, a raw loose density of from 3 to 40 pcf, a thermal conductivity "k" factor of from 0.25 to 0.40 BTU. in/hr..degree.F.ft.sup.2 and a fusion point of from 1600.degree. C. to 1700.degree. C. The composition also comprises an organic binder such as starch or latex, a mineral binder of the silicate type such as sodium or potassium silicate, or a mixture thereof. If desired, the composition may further comprise reinforcing fibers in such an amount as to give sufficient strength to the composition to make it operative depending on the intended use of the article produced therefrom. This composition can be used in particular to produce fire proofing boards.
