It can effectively reduce the stress of bottom by substituting for corundum
castables in bottom lining.
Average defect depth is determined on titanium surfaces after blasting with corundum
particles with two different acidic mixtures as shown in Table 5 .
In the sodium reduction process in use at the time, the crushed corundum
first had to be converted chemically into aluminum chloride and then reduced with sodium to form salt and metallic aluminum.
The prosthesis was made from a titanium alloy with a corundum
rough-blasted surface for implantation using either a cement or press-fit technique.
Ash piping, chutes, fan blades, air separators lined with Abresist fused cast basalt, alumina ceramic or Kalcor alumina zirconia corundum
Garnet, titanite, amphiboles, pyroxenes, and possibly also corundum
have partially dissolved in poorly cemented sand- and siltstones, which alternate with layers of carbonate and argillaceous rocks.
can scratch quartz, but cannot scratch diamond;
Another hypothesis for the polish on the Stone Age corundum
ax head is that the Stone Age people never had absolutely pure corundum
, which indeed would have required diamond to polish ("In the Buff: Stone Age tools may have derived luster from diamond" SN: 2/19/05, p.
Suitable disperse phases were found to be corundum
Kyanite, garnet, monazite, and amphibole are common minerals, while apatite, anatase, titanite, corundum
, pyroxene, and epidote are rare.
All of these rocks are peraluminous and contain normative corundum
, except for the most mafic enclaves.
The glass samples were finely divided in corundum
mortars, then dissolved in nitric acid, and 100 mL dilute solutions were prepared for AA analysis.
