“…In nature, boron is found in the form of boric acid or borate salts. Boric acid, borax, borax hydrates and sodium perborates are all commercially important boron compounds [14]. They are used in a wide range of applications in agriculture as well as in detergents, wood treatments, fibreglass, glass and ceramics.…”

The corrosion behaviour of AISI 316 and AISI 304 stainless steels in Na 2 B 4 O 7 ·5H 2 O solutions with various concentrations (3%, 6% and 9% w/w) commonly used in wood industry was investigated by using electrochemical impedance spectroscopy and polarisation techniques. The results reveal that the dissolution pattern of the studied steel samples is in the order 3% > 6% > 9%. The AISI 316 stainless steel is found to exhibit better corrosion resistance than the 304-type stainless steel alloy.

“…On the other hand, some studies have been carried out in Turkey to recover boron from BW by leaching using various solutions. 16,17 Turkish standard TS EN 14411 18 defines terms and establishes classifications, characteristics and marking requirements for ceramic tiles of the best commercial quality. Table I shows the classification of dry-pressed ceramic tiles according to their groups and their specific product standards.…”

In the present study, dissolution unit's waste of Kirka borax mine, Turkey (BW) was employed in different amounts as a partial substitution for the marble in order to develop an experimental wall tile body composition. A series of ceramic tile formulations were prepared with 2, 4, 6 and 9 wt% of BW incorporation into the batch compositions and shaping by dry pressing under laboratory conditions. The obtained samples were single fast-fired at a peak temperature of 1150 o C for a total firing time of 38 min (from cold-to-cold) under industrial conditions. Some technological properties of the resultant products, namely linear firing shrinkage, water absorption and bending strength were determined as a function of increasing BW content in place of marble at these temperatures. The phase contents of the starting raw materials and fired compositions of BW were determined by XRD. The relevant polished surfaces of selected fired samples were examined using SEM and EDX. According to the results, increased presence of BW compared to the standard wall tile formulations accelerated the vitrification process and improved the physical properties of the body. The overall results indicated a prospect for using the BW as a raw material up to 4 wt% for the production of a wall tile body, and with this recipe lower firing regime than that applied at the factory (1150 o C), could be employed. Rheological behaviour of the R2 formulation containing 4 wt% BW was studied as a function of the deflocculant amount by means of viscosity analysis. It is possible to produce a wall tile at 1100 o -1120 o C according to Turkish Standard TS EN 14411.
