Abstract

Vermiculite, a hydrated Mg/Al/Fe silicate mica-like clay mineral with a laminate structure. Vermiculite is a very versatile material. It has a remarkable ability to expand to many times its original volume (exfoliation) when heated (>300°C). The majority of applications call for vermiculite in its exfoliated form, and it has a wide range of applications that take advantage of its significant properties such as low bulk density, low thermal conductivity, odor-free, chemical inertness, easy handle and fire resistance. These properties make vermiculite a promising material for use as high-temperature insulating refractory material in the metallurgical industry.

Highlights

Vermiculite, a hydrated Mg/Al/Fe silicate mica-like clay mineral with a laminate structure
In other words, heatinsulating materials used as additions to mixtures with very high porosity generally provide an effective definitely mean of reducing the apparent density and improving the demand for efficient up to date heat insulating materials essentially has become urgent in the development of ladle metallurgy in a very big way [1]
Insulation materials kind of reduce heat flow in linings, and they limit the transfer of heat conductivity, convection or both, which generally essentially is fairly significant in a subtle way [3]

Summary

Introduction

Vermiculite, a hydrated Mg/Al/Fe silicate mica-like clay mineral with a laminate structure. Production and utilization of sort of high-temperature heat insulating materials basically make it possible to much lower the consumption of material in thermal machines, to mostly reduce by 9-10 times in the weight of the furnaces. Insulation materials kind of reduce heat flow in linings, and they limit the transfer of heat conductivity, convection or both, which generally essentially is fairly significant in a subtle way [3].
