A technique of induction smelting followed by directional solidification to recover and purify silicon from diamond wire saw waste powder without the use additives is presented herein. The reaction effect time on removal impurities were investigated using a simple method. Through detection byproducts condensed volatiles, it inferred that Si volatilized removed as monoxide during smelting. Bypro...

In electrolytic in-process dressing (ELID), a metal-bonded grinding wheel is dressed as a result of anodic dissolution. In this paper we describe experiments to evaluate the potential for ELID on bronze wheels in fixed-load grinding applications. A constant-force grinding apparatus was used to determine appropriate ELID conditions for a 10-20 \xm bronze bonded diamond grinding wheel used to mac...

Monocrystalline silicon slicing is the first step in making chips, and surface quality of wafers directly affects later processing accounts for a large proportion chip manufacturing cost. Ultrasonic vibration assisted wire saw (UAWS) an effective sawing process cutting hard brittle materials such as monocrystalline Si, which can significantly improve wafers. In order to further study formation ...

This study evaluated the effect of specimens’ design and manufacturing process on microtensile bond strength, internal stress distributions (Finite Element Analysis FEA) and specimens’ integrity by means of Scanning Electron Microscopy (SEM) and Laser Scanning Confocal Microscopy (LCM). Excite was applied to flat enamel surface and a resin composite build-ups were made incrementally with 1-mm i...

Laser sawing of diamonds is beginning to revolutionize the diamond-cutting industry. Not only does the laser saw offer savings in time and money, but it also enables the cutting of material virtually unworkable by conventional methods and makes available an almost limitless assortment of fancy shapes. This article describes the components and operation of the laser saw, as well as the situation...

Silicon is a material well suited for refractive lenses operating at high X-ray energies (>50 keV), particularly if implemented in a single-crystal form to minimize small-angle scattering. A single-crystal silicon saw-tooth refractive lens, fabricated by a dicing process using a thin diamond wheel, was tested with 115 keV X-rays, giving an ideal 17 microm line focus width in a long focal length...
