Expert Reviews

Dr. Baron Augustin, Ph.D (TUM), (Technical University of Munich, Germany)

Potassium Borate: Nanoshel’s Potassium Borate is a product resulting from the controlled reaction of potassium hydroxide, water and boric acid. It is an alkaline salt with excellent buffering properties and consists of white crystalline granules. Potassium tetra borate replaces borax where an alkali borate is needed but sodium salts cannot be used

Dr. Darren Chandler, Ph.D, (Manchester Metropolitan University, U.K)

Potassium Borate:  hydrolyzes to give a mildly alkaline solution. It is thus capable of neutralizing acids. It also combines with strong alkalis to lower their pH. The pH of a 2% (wt.) solution of potassium borate is 9.2. The value increases very slightly with increasing concentration, and diminishes very slightly with increasing temperature.

Dr. Ms. Cristiana Barzetti, (University of Cagliari-Department of Chemical Engineering and Material Science, Italy)

Potassium Borate: Nanoshel’s Potassium Borate is an excellent solvent for metallic oxides at high temperatures. In the field of metallurgy, it is used in the preparation of special welding, soldering and brazing fluxes of stainless steel or various non-ferrous metals to avoid the “glare” associated with sodium borate.

Dr. Mark Brown, (Georgia Institute of Technology in Atlanta, USA)

Potassium Borate:  dispersed in a very finely divided state, improve the load carrying, anticorrosion, and antiwar properties of industrial and automotive gear lubricants. Under extreme conditions, potassium borates interact with metal load-bearing surfaces to form a film of extraordinary resilience. This tenacious film provides outstanding load-carrying capacity and wear protection.

Dr. Jang Huang, Ph.D, (Shandong Science and Technology University, China)

Potassium Borate:  shows little tendency to cake except after prolonged storage or if it becomes severely wetted by rain or substantial water penetration. It is also capable of absorbing moisture if exposed to a humid environment. When stored under normal conditions of temperature and humidity, potassium Borate is unlikely to change chemically or cake.
