Usage of vermiculite as a high-temperature insulating refractory material

Year 2018, Volume: 1 Issue: 2, 13 - 19, 31.12.2018

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. The service (working) temperature of vermiculite-based refractories is about 1100-1150 °C. In order to increase the working temperature and to produce a wide range of vermiculite-based refractory products, refractory binders and fillers (e.g. alumina cement, fire clays etc.) are added to the lightweight vermiculite. In this paper, the application of vermiculite as a high temperature insulating refractory material was mentioned.

Vermikülitin yüksek sıcaklık refakter yalıtım malzemesi olarak kullanımı

Year 2018, Volume: 1 Issue: 2, 13 - 19, 31.12.2018

Abstract

Vermikülit, laminar bir yapıya sahip hidratlanmış Mg / Al / Fe silikatlı mika benzeri bir kil mineralidir. Vermikülit çok yönlü bir malzemedir. Isıtıldığında (>300°C) orijinal hacminin birçok katına kadar genişleme yeteneğine sahiptir. Vermikülit minerali düşük kütle yoğunluğu ve ısıl iletkenlik, kokusuz olması, kimyasal inertlik, kolay tutuşma ve yangına dayanıklılık gibi önemli özelliklerinden yararlanılan geniş bir uygulama alanına sahiptir. Bu özellikler, vermikulitin metalurji endüstrisinde yüksek sıcaklıkta yalıtkan refrakter malzeme olarak kullanılmak üzere uygun bir malzeme olmasını sağlar. Vermikülit bazlı refrakterlerin servis (çalışma) sıcaklığı yaklaşık 1100-1150 °C’dir. Çalışma sıcaklığını arttırmak ve çok çeşitli vermikülit bazlı refrakter ürünler üretmek için, hafif vermikulite refrakter bağlayıcılar ve dolgu maddeleri (örn. alümina çimento, ateş kili, vb.) ilave edilir. Bu yazıda vermikulitin yüksek sıcaklıkta yalıtkan refrakter malzeme olarak kullanılmasından kısaca bahsedilmiştir.
