Abstract
This study explores the powder metallurgy methods for obtaining slag-containing composite materials that can be utilized in the ceramic industry, and especially in catalysis, as raw materials for the production of building materials, and also as refractories. The main components of the synthesized samples of composite materials are natural aluminosilicates from the east of Kazakhstan and metallurgical slag of lead production. Varying the content of components in the range: slag 10-30 wt.%, bentonite clay 30-40 wt.%, and natural zeolite 40-60 wt.%, a pilot batch of composite materials was obtained. The results show that the samples had high mechanical strength, ranging from 20.7 to 50.53 MPa, after sintering at a temperature of 1000 °C.
