摘要：
Results of a study of the heat resistance of chamotte refractories as a function of the composition of their binder are presented. The introduction of a refractory particolored clay or clay DN2 rich with alkaline and alkaline-earth oxides into chamotte-kaolin mixtures hampers the formation of cristobalite. The cristobalite effect and the temperature coefficient of linear expansion of the specimens decreases up to a temperature of 600 degrees C, which enhances their heat resistance.
