Claim 2
Dependent Claim
24 words
The composition having the general formula x[(NHNH.sub.2).sub.3 CNO.sub.3 ]·(1-x) [(NHNH.sub.2).sub.3 C).sub.2 B.sub.10 H.sub.10 ] wherein the value of x is between 0.01 and 0.99.
Claim 3
Dependent Claim
15 words
The composition of claim 1 wherein the value of x is between 0.5 and 0.99.
Claim 4
Dependent Claim
49 words
A mixture comprising an intimate physical blend of the triaminoguanidinium salt of decahydrodecaborate acid, (C(NHNH 2 ) 3 ) 2 B 10 H 10 and triaminoguanidine nitrate, (NHNH 2 ) 3 CNO 3 , wherein said nitrate comprises from between approximately 1% and 99%, by weight, of said mixture.
Claim 5
Dependent Claim
49 words
A mixture comprising an intimate physical blend of the triaminoguanidinium salt of decahydrodecaborate acid, (C(NHNH 2 ) 3 ) 2 B 10 H 10 and triaminoguanidine nitrate, (NHNH 2 ) 3 CNO 3 , wherein said nitrate comprises from between approximately 1% and 99%, by weight, of said mixture.
Claim 6
Dependent Claim
142 words
A product having the formula: x[(NHNH.sub.2).sub.3 CNO.sub.3 ]·(1-x)[ ((NHNH.sub.2).sub.3 C).sub.2 B.sub.10 H.sub.10 ] wherein the value of x varies between 0.01 and 0.99 said product being formed by a coprecipitation process between the triaminoguanidinium salt of decahydrodecaboric acid and triaminoguanidinium nitrate by the steps of: (A) dissolving both said decahydrodecaborate salt and said nitrate in a mutually soluble solvent, at a temperature sufficiently high to maintain said salt and said nitrate in solution; (B) forming a pressurized stream of said solution and bringing said solution stream together with a pressurized stream of a miscible nonsolvent, under conditions of extreme turbulence within a mixing chamber, to effect a substantially complete coprecipitation; (C) recoverning the coprecipitated product by filtering the effluent from said mixing chamber, and washing said product with an inert and nonsolvent fluid; (D) drying the product to remove all remaining liquid.
Claim 7
Dependent Claim
142 words
A product having the formula: x[(NHNH.sub.2).sub.3 CNO.sub.3 ]·(1-x)[ ((NHNH.sub.2).sub.3 C).sub.2 B.sub.10 H.sub.10 ] wherein the value of x varies between 0.01 and 0.99 said product being formed by a coprecipitation process between the triaminoguanidinium salt of decahydrodecaboric acid and triaminoguanidinium nitrate by the steps of: (A) dissolving both said decahydrodecaborate salt and said nitrate in a mutually soluble solvent, at a temperature sufficiently high to maintain said salt and said nitrate in solution; (B) forming a pressurized stream of said solution and bringing said solution stream together with a pressurized stream of a miscible nonsolvent, under conditions of extreme turbulence within a mixing chamber, to effect a substantially complete coprecipitation; (C) recoverning the coprecipitated product by filtering the effluent from said mixing chamber, and washing said product with an inert and nonsolvent fluid; (D) drying the product to remove all remaining liquid.
Claim 8
Dependent Claim
50 words

Claim 9
Dependent Claim
33 words
The composition of claim 1 wherein further the composition is a coprecipitate and the substituent ions B 10 H 10 -2 and NO 3 - are intimately intertwined through interlattice and intercrystalline mixing.
Claim 10
Dependent Claim
58 words
The coprecipitate of claim 6 wherein the value of x is between 0.5 and 0.99, and said coprecipitate is the product of a process comprising the steps of dissolving the triaminoguanidinium salt of decahydrodecaboric acid and triaminoguanidinium nitrate in water to form a solution and simultaneously precipitating the constituent ions by adding said solution to a miscible nonsolvent.
Claim 11
Dependent Claim
13 words
