Abstract

Purpose

The purpose of this paper is to propose a new method of synthesis of CuO · SiO2 oxide composite based on the reaction of precipitation from water solutions of sodium silicate and copper nitrate.

Design/methodology/approach

Solutions of sodium silicate and copper nitrate were used as substrates. The effects of direction of substrate supply, concentration, excess of reagents and temperature of precipitation on the physicochemical properties of the products were analysed.

Findings

A new method of synthesis of CuO · SiO2 oxide composite based on a precipitation reaction is proposed.

Research limitations/implications

Only sodium silicate and copper nitrate solutions were used.

Practical implications

The CuO · SiO2 oxide composite obtained can be used as blue pigment or polymer filler.

Originality/value

The paper determines optimum conditions of CuO · SiO2 oxide composite precipitation to obtain products with desired physicochemical, dispersive and structural properties.
