Explosive formulations of mixture of carbon dioxide and a reducing agent and methods of using same
The disclosure relates to embodiments of an explosive formulation comprising a detonable mixture of an oxidizing agent such as carbon dioxide, and a material that decomposes the oxidizing agent exothermically (a reducing agent), and additives that increase the mixture's shock sensitivity. The formulations may be used in a method to produce diamonds or nano oxides or in other applications that use traditional explosives such as, but not limited to: ammonium nitrate and fuel oil combinations (ANFO), watergel explosives, emulsion explosives and RDX.
Additive raw material composition and additive for superhard material product, preparation method of the additive, composite binding agent and superhard material product, self-sharpening diamond grinding wheel and preparation method of the same
Disclosed are an additive raw material composition and an additive for superhard material product, a composite binding agent, a superhard material product, a self-sharpening diamond grinding wheel and a method for manufacturing the same. The raw material composition consisting of components in following mass percentage: Bi.sub.2O.sub.3 25%˜40%, B.sub.2O.sub.3 25%˜40%, ZnO 5%˜25%, SiO.sub.2 2%˜10%, Al.sub.2O.sub.3 2%˜10%, Na.sub.2CO.sub.3 1%˜5%, Li.sub.2CO.sub.3 1%˜5%, MgCO.sub.3 0%˜5%, and CaF.sub.2 1%˜5%. The composite binding agent is prepared from the additive and a metal composite binding agent. The self-sharpening diamond grinding wheel prepared from the composite binding agent has high self-sharpness, high strength, and fine texture, is uniformly consumed during the grinding process, does not need to be trimmed during the process of being used, and maintains good grinding force all the time, fundamentally solving the problems of long trimming time and high trimming cost of the diamond grinding wheel (FIG. 1).

Boron compound suspension
A suspension of a boron containing compound in the form of crystals, powder or granulate in a solvent which contain a carbomer as dispersant. This suspension is very stable, even at high concentrations, and exhibits favourable non-Newtonian viscosity behavior, which makes it suitable in a number of applications, such as for the control of fission reactions with the generation of electric power from nuclear energy.

Boric Acid Purification Process
The present disclosure is directed to a process. In an embodiment, the process includes providing a boric acid solution composed of from 10 wt % to 25 wt % boric acid at a temperature from 60 C. to less than 100 C. to form a heated boric acid solution. The process includes first passing the heated boric acid solution through a first nanofiltration membrane at a pressure from 300 psi to 500 psi to form a first heated boron permeate and second passing the first heated boron permeate through a second nanofiltration membrane at a pressure from 300 psi to 500 psi and forming a second heated boron permeate. The second heated boron permeate is composed of at least 10 wt % boric acid, less than 5 ppm sodium, and less than 5 ppm of a component selected from calcium, lithium, sulfur, and silicon.
