MINERAL FIBERS SUSCEPTIBLE TO DISSOLVE IN A PHYSIOLOGICAL ENVIRONMENT.

摘要

THE PRESENT INVENTION CONCERNS COMPOSITIONS OF MINERAL FIBERS SUSCEPTIBLE TO DISSOLVE ON CONTACT OF A PHYSIOLOGICAL ENVIRONMENT. THE FIBER COMPOSITIONS INCLUDE THE FOLLOWING CONSTITUENTS, ACCORDING TO THE DEFINITIVE WEIGHT PROPORTIONS BELOW: SIO2 FROM 48 TO 67%, AL2O3 FROM 0 TO 8%, FE2O3 FROM 0 TO 12%, TOTAL OF 16 At 35%, MGO from 1 to 16%, NA2O + K2O from 0 to 6.5%, P2O5 from 0 to 5%, CONSIDERING THAT THE COMPOSITIONS ARE EQUALLY DEFINED BY THE FACT THAT THE CONTENTS OF THE CONSTITUENTS RESPECT THE FOLLOWING RELATIONS: NA2O + P2O5 2%, FE2O3 + AL2O3 12%, CAO + MGO + FEO3 23%.
