Properties of Refractories - Mu

Alumina refractory materials that consist of aluminium oxide with little traces of impurities are known as pure alumina. Alumina is one of the most chemically stable oxides known. It is mechanically very strong, insoluble in water, super heated steam, and most inorganic acids and alkalies. Its properties make it

Refractory Materials — The function of Refractory Materials

31.10.2016· Refractory material should have no easy to melt performance under the action of high temperature. High temperature structural strength is large. Refractory materials should not only have high melting temperature, but also should not happen softening deformation and collapse under the stove masonry load or other mechanical shock.

Microstructure and properties of a refractory NbCrMo0.5Ta0

25.11.2011· The refractory metals and alloys, a group of metallic materials with melting points above 2123 K, are creep resistant at temperatures above 1073 K. High temperature strength and creep resistance are the key properties of these alloys, since considerable alloy softening generally occurs at temperatures above ∼0.5–0.6 T m, where T m is the absolute melting temperature. At the same time, …

Refractories: Properties and Types | Engineering

21.04.2018· A good refractory material should have the following properties: 1. It should be able to withstand high temperatures generated in the furnace.

Characteristics of Refractory Materials for Hazardous

09.11.2020· Pure magnesia refractories have very poor resistance to alkaline residues. However, when magnesia-alumina spinel is added to magnesia materials, it can well prevent the permeability of alkaline residues to refractory materials. And as the amount of magnesia-alumina spinel added increases, the penetration resistance will gradually become stronger, but the additional amount should not exceed …

Types of Refractory Materials and Their Appliions

Silica: Pure silica melts at a very high temperature, namely 1713°C, but when it comes in contact with alkaline substances, it forms silies, some of which melt easily. Therefore, the presence of alkali in silica used as a refractory material should be avoided. Silica occurs in the form of quartzite, Dinas rock and ganister. Ganister is a rock with a high content of natural silicon (98% SiO2).
