The process of manufacturing of cordierite-mullite pipes from natural resources which contribute MgO, Al 2 O 3 and SiO 2 , consisting in introducing the materials in the form of granulate, in which the share of MgO ensures after firing achieving the contents of 30-45% of cordierite weights, and the part which contributes this ingredient - talc, has been replaced with micronised natural cordierite in the amount of 5-10% weights. |
