N.B. SEE ALSO 1C107.
a. Ceramic powders of titanium diboride (TiB2) (CAS 12045-63-5) having total metallic impurities, excluding intentional additions, of less than 5 000 ppm, an average particle size equal to or less than 5 μm and no more than 10 % of the particles larger than 10 μm;
b. Not used;
c. Ceramic-"matrix" "composite" materials as follows:
1. Ceramic-ceramic "composite" materials with a glass or oxide-"matrix" and reinforced with any of the following:
a. Continuous fibres made from any of the following materials:
1. Al2O3 (CAS 1344-28-1); or
2. Si-C-N; or
Note:
1C007.c.1.a. does not control "composites" containing fibres with a tensile strength of less than 700 MPa at 1 273 K (1 000 °C) or tensile creep resistance of more than 1 % creep strain at 100 MPa load and 1 273 K (1 000 °C) for 100 hours.
b. Fibres being all of the following:
1. Made from any of the following materials:
a. Si-N;
b. Si-C;
c. Si-Al-O-N; or
d. Si-O-N; and
2. Having a "specific tensile strength" exceeding 12,7 × 103 m;
2. Ceramic “matrix” "composite" materials, with a "matrix" formed of carbides or nitrides of silicon, zirconium or boron;
d. Not used;
e. 'Precursor materials' specially designed for the "production" of materials specified in 1C007.c., as follows:
1. Polydiorganosilanes;
2. Polysilazanes;
3. Polycarbosilazanes;
f. Not used.
Technical Note:
For the purposes of 1C007, 'precursor materials' are special purpose polymeric or metallo-organic materials used for the "production" of silicon carbide, silicon nitride, or ceramics with silicon, carbon and nitrogen.
