Product parameters

Executive standard: Q/TY·J08.22-2018

English alias: Boron Powder, Monomer Boron

CAS RN: 7440-42-8

1. Physical and chemical properties：

1.1 Decomposition temperature of adhesive: <200℃
1.2 Solubility: The binder in agglomerated boron is insoluble in organic solvents such as ethanol and ether, but soluble in water.
1.3 Properties: Stable at room temperature. When heated to 200℃, the binder in the agglomerated boron is decomposed and dispersed into fine elemental boron particles, which will burn at 700℃ and can be used as a high calorific value fuel.

2. Technical indexes：

Note: *Based on the addition of 92% of the total boron content of amorphous element boron.

3. Application: Agglomerated boron for propellant is mainly used in solid rocket ramjet engines. It is a high-energy fuel for fuel-rich propellant. This product uses a binder to agglomerate fine element boron particles into micron particles, which solves the problem of fine element boron in the propellant. The problem of limited particle addition; moderate agglomerated boron strength solves the compatibility problem of the hydroxyl-terminated binder prepolymer, and can also adjust the fuel performance of the propellant.

4. Safety instructions: Toxic by ingestion and inhalation. The damage of central nervous system, stomach and intestinal stimulation, ig. boron poisoning, are caused by inhalation of boron. Eyes bear slight stimulation as well. Be handled with rubber gloves, a respirator and eye protection by wearing protective clothing.

5 Packing: Vacuum-packaging. Aluminum foil bag with plastic bag, 1 kg net each.

6. Storage: Stored at cool, dry and ventilate place. The shelf life is 12 months after manufactured date. It is still available if the retest results of the properties are qualified after expired date

7. Transportation：Avoid rain, sunlight and crash. Do not mix with strong oxidizer.
