Properties of Clinker Ceramics based on Low- and High-Melting Raw Materials from the Siberian Region

Abstract

In the production of ceramic materials and products, clinker ceramics leaves behind traditional ceramics in mechanical properties, durability and resistance to external influences. However, the production cost plays a crucial role in feasibility of clinker ceramics production, so the key task in the production chain is a selection of available local raw materials.

Purpose: The aim of this work is to study raw materials from the Siberian region and their testing to produce clinker ceramics. The paper describes the experience of using raw materials in the form of low-melting red-burning clay from the Voroninsky deposit, refractory lightburning clay from the Kailinsky deposit and mineral additive albitophyre for the clinker ceramics production.

Research findings: Raw materials properties are studied to obtain clinker ceramics with specific composition. Technological properties of mixture components and calcinated ceramics are determined. It is shown that calcination of mixture components (45 % of clay from Voroninsky deposit, 40 % of clay from Kailinsky deposit, 15 % of albitophyre) at 1100 °C for 8 hours, allows to produce clinker ceramic products with the ceramic body water absorption of 2.70 to 2.98 %.
