To determine the possibility of using a mineral pigment based on the rutile form of titanium dioxide in the production of volume-colored ceramic brick in order to obtain lighter brick tones the studies are conducted. The previously studied low-melting clay of the Tyumen deposit was used as a basis. It was established that significant lightening of the brick does not occur even with the introduction of 8% of the specified pigment, although some lightening is appeared. In addition, with the pigment introduction, an increase in water absorption of bricks is observed, which leads to a decrease in the sample strength. Increasing the firing temperature to 950degC does not lead to an improvement in the quality characteristics of the samples, and even vice versa makes them worse. Thus, the use of a white pigment under investigation does not give a significant effect of lightening of ceramic red-burning clay. |
