The aim of the study was to evaluate the effect of simulated porcelain firing cycles and surface finishing on the marginal fit of commercially pure titanium (Cp Ti) copings.A machined stainless steel die system with standard 0.5-mm copings was fabricated. Wax patterns were prepared by pouring the molten wax on a two-part stainless steel die.

Suspension firing of reject coal fines Quebec iron and titanium company
1978A pilot-scale experimental project to establish the flame stability and combustion characteristics of reject coal fines in a swirl-stabilized flame is described. The coal fines were found to require 25% of the thermal input to the flame as either distillate oil or gas to produce an adequately stable flame. When this level of support was used combustion

"Towards 100 TW -10 Hz titanium-sapphire laser facilities: The European FIRE project"
Novel Lasers and Devices-Basic Aspects, 1999Experimental ultra-intense light-matter interaction has now reached the level of petawatt powers using large-aperture Nd.glass laser systems [1], even if only at high costs per shot and very low repetition rates. If, on the other hand, ultra-high field strength and repetition rate is of more concern than maximum pulse energy, as is typical for basic ...

Heterogeneous photocatalysis can be exploited for the decomposition of micro-organisms which have developed on the surfaces of building materials. In this work, the efficiency of titanium dioxide coatings on fired clay products is examined. The sol-gel method is used to synthesize a fine TiO2 powder with a specific surface area of 180 m2 g−1.

Hot work on a steam condenser ignites a titanium tube bundle fire: A case history
Process Safety Progress, 1997AbstractThe flammability of titanium chips, fines, and powders is widely recognized. Titanium alloy tubing is much more difficult to ignite. However, as this paper describes, titanium tubing in heat exchangers is subject to ignition as a result of hot work operations. Explosions can follow if water is applied to the burning titanium.A fire consumed the

[Color stability of porcelain-fused-to-titanium restorations after repeated firings].
Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae, 2005To study the effect of repeated firings on color of porcelain-fused-to-titanium restorations.Twenty standard porcelain-fused-to-titanium specimens were made with Dentsply DETREY TiBond C3 and Dentaurum rematitan Til. Then they were fired 1, 2, 4, 7, and 10 times.

A significant attempt has been made to enhance the flammability property of polymer composites that are used in the aircraft structural application. With cumulative interest in carbon fabric reinforced epoxy polymeric composites, it is imperative to enhance the fire-resistant property of these materials.

Titanium in a hyperbaric oxygen environment may pose a fire risk.
Aviation, space, and environmental medicine, 2004The use of titanium during hyperbaric oxygen therapy may pose a risk of fire. A fresh titanium surface in a high oxygen atmosphere can be a source of ignition. The clinical scenario may be a patient who accidentally breaks his titanium-framed glasses during a hyperbaric oxygen treatment in a monoplace chamber or using an oxygen hood.
