Unique Design Alternative- Harper Vertical Furnace
conveyor furnace, screw feeders provide all of the motive force to push the reactants into the hot zone. The system's specialized material movement limits the potential for overheating problems, such as melting/sublimation, sintering or excessive grain growth. In addition to the container-less nature of the design, thermal transfer between product and reactants significantly improves the power efficiency of the unit. Harper's philosophy is not only to deliver comprehensive systems with the latest... (read more)

ROTRONIC HYGROLAB C1 and Seed Storage
Seed storage with ROTRONIC products. . Seed storage in general. . Around 10,000 years ago, the first humans stopped hunting and gathering wild plants and instead started to cultivate on farms, preserving and storing seeds became important. There are various reasons to store seeds, starting from simply preserving grain for consumption later in the year or as sowing for the next season. A little more complex is the collection and preservation of seeds for a longer period of time... (read more)

Sintered alpha Silicon Carbide Some Aspects of the Microstructure - Strength Relationship (.pdf)
Alpha silicon carbide billets, 98% of theoretical density, were formed by cold pressing and sintering. One half of this fine grain sintered material was further heat treated to induce exaggerated grain growth thus producing a coarse grain micro-structure.
New Perspective of Flux Assisted GTA Welding in Titanium Structures (.pdf)
Welded titanium structures are exposed to severe conditions in corrosive environments. Titanium alloys are sensitive to grain growth and atmospheric contamination during welding. Gas tungsten arc welding (GTAW) is largely used for joining titanium parts. However, in case of thick components
Assessment of Eutectic Solder Phase Growth in Under-The-Hood Power Control Modules (.pdf)
In many applications, especially automotive, solder interconnects experience degradation due to prolonged temperature and power cycling. This degradation behavior manifests itself as changes in the grain/phase structure, primarily through grain/phase coarsening. Because the magnitude of the change
Advanced Reactor System for the Fine Control of Properties of Molybdenum Powder
Extensive investigation in the two-stage hydrogen reduction process for fine molybdenum powder synthesis has been con-ducted. Reaction thermodynamic, kinetics, grain morphology transformation mechanism, grain morphology and grain size control have been studied in detail. Pilot scale development
OIM Analysis of Indium Oxide Thin Films (.pdf)
The crystallography and texture of oxide thin films have been studied using Orientation Imaging Microscopy (OIM). The crystallography of both the growth interface and the grain boundaries within the film has been studied. In this example, In2O3 is grown as a thin film on a MgO substrate. Results
The State of the Art In Gas Cleaning for the Fertilizer Industry
The fertilizer industry has earned recognition for having contributed directly to increase world grain yields in the past century. Based on the conservative estimate of the world population growth, total fertilizer use in the future is expected to grow more than 200 million tons from the current
