A mix composition has been developed making it possible to obtain on the basis of diatomite from the Inzenskoe deposit (Ul’yanovsk Oblast’) a heat-insulating brick with good strength characteristics exceeding previous values by a factor of 4 – 5: compression strength 5.5 – 6.5 MPa, density 0.5 – 0.6 kg/cm3, thermal conductivity at 25°C 0.09 W/(m · K), and structure factor 0.95.
