Source sentences:
text: The present invention is such a refractory body, and is prepared in a manner such that it contains doped cordierite having from about 47.5 to about 56 weight percent SiO 2 , from about 31 to about 40 weight percent Al 2 O 3 , from about 12 to about 19 weight percent MgO, from about 0.15 to about 1.0 weight percent CaO, from 0 to about 250 ppm Na 2 O, and from 0 to about 150 ppm K 2 O, the cordierite being prepared using synthetic raw materials, the body having a flexural strength of at least about 20,000 psi as measured using a 4 point bend test.
