16 Claims

1. A composite material comprising:

a) activated and ground sodium hexametaphosphate frit particles obtainable by means of a thermal activation method comprising the steps of:

i) heating a sodium hexametaphosphate salt until it melts such that a molten sodium hexametaphosphate salt is obtained;

ii) abruptly cooling the molten sodium hexametaphosphate salt obtained in step (i) in a dry medium to obtain activated sodium hexametaphosphate frit particles; and

iii) grinding the activated sodium hexametaphosphate frit particles obtained in step (ii) to obtain activated and ground sodium hexametaphosphate frit particles; and

b) a polymer matrix;

wherein said composite material comprises the activated and ground sodium hexametaphosphate frit particles in a mass percentage less than 60%; and

wherein said activated and ground sodium hexametaphosphate frit particles are embedded in said polymer matrix.
