Corrosion Mechanism of MgO–CMA–C Ladle Brick with High ...
3 Results and Discussion. Figure 1 displays the condition of the newly developed ladle lining after 138 cycles in comparison with a MgO–C lining after 132 cycles. In contrast to a common MgO–C lining without CMAaddition (end of service life after 132 cycles with a much worse condition), on the hot face of MgO–C with CMA, a slag coating was formed.
Chrysotile: Mineral information, data and localities.
This mineral is known to be a respirable carcinogen, and is the most common form of asbestos. Exposure to very dusty air or longterm exposure to low level airborne dusts containing fine fibres of chrysotile has been found to cause a high risk of serious lung disease including mesothelioma and lung cancer.

Petrology of a Melilite–Olivine Nephelinite from Hamada ...
Abstract. A melilite–olivine nephelinite lava flow occurring in Hamada, SW Japan, is the most silicaundersaturated lava known to have erupted in Japan (SiO 2 content ∼37 wt %), and may be a least fractionated melt from mantle depths. Heterogeneity of elements such as Si, Al, Ca, and alkaline elements is one of the characteristic features of the Hamada nephelinites and is attributed to ...

LABORATORY CORROSION TESTS OF ROTARY LIMEKILN REFRACTORIES ...
Abstract A modifiion of the Hugill, Ainsworth, and Green laboratory method for determining the corrosive action of lime on refractories was used to indie the best refractory for rotary limekilns. An intermediate handmade refractory, two high alumina, two superduty, and two first‐quality, stiff‐mud refractories were tested. It was found that the depth of penetration of the lime attack ...

New Strategy toward Coal Combustion by ...
A large amount of sulfur dioxide (SO2) will be released during rural coal combustion, causing serious environmental pollution. Therefore, it is very urgent to develop a clean and efficient fuel to substitute rural coal controlling SO2 emission. In this paper, a new strategy toward stered coal combustion with remarkably reducing SO2 emission was proposed. Coal and ...
