Tracy Hall, along with Francis Bundy, Robert Wentorf, and Herbert Strong, had synthesized diamond from carbon in a process that was reproducible. Scientists knew that graphite, a pure carbon substance, was needed to produce manmade diamonds. The GE researchers discovered that graphite was resistant to change due to strong bonding of the carbon atoms. By utilizing iron as a catalyst to free the carbon bonds and by applying high pressure and high temperature, they were able to turn graphite into manmade diamonds. The first successful reproducible experiment was completed on the morning of December 16, by Hall in his unique "Belt" apparatus. Diamonds have a wide variety of applications because of their exceptional physical characteristics, including hardness and heat conductivity, making them ideal for use in cutting, grinding, and polishing. Today, over tons or over million carats of synthetic diamonds are produced annually for industrial use. Originally from Ogden, Utah, Hall received his B. There he invented additional apparatus and products and founded several companies that manufacture diamonds and high-pressure equipment. Plan Your Visit Exhibits. Back to Inductee Search H. Tracy Hall Diamond Synthesis. Patent No. Born Oct.
Hall returned to the University of Utah inwhere he was Henry Eyring 's first graduate student, dr tracy hall, and was awarded his PhD in physical chemistry in Hall was one of a group of about a half dozen researchers who had focused on achieving the synthesis for almost four years. Born Oct.
Howard Tracy Hall October 20, — July 25, was an American physical chemist and one of the early pioneers in the research of synthetic diamonds , using a press of his own design. Howard Tracy Hall was born in Ogden, Utah in He often used the name H. Tracy Hall or, simply, Tracy Hall. He was a descendant of Mormon pioneers and grew up on a farm in Marriott, Utah. When still in the fourth grade, he announced his intention to work for General Electric. For the next two years, he served as an ensign in the U.
Diamonds are the subject of one of the great battles between the forces of Marketing and the forces of Matter. In one corner is DeBeers, with the best advertising slogan of the 20th Century , "Diamonds are Forever. Tracy Hall was the first guy to turn carbon into diamonds. He died last week at age The L. Times has the best obituary of Hall that I've seen. I got a kick out of all the tinkering he had to do before he hit on the right contraption for cooking up diamonds: "Hall had built a pressure chamber that he called the "half-belt" that had been used to create high pressures in a year-old Watson-Stillman press that leaked so much water from its hydraulics that he had to wear rubber boots while working with it. My eyes had caught the flashing light from dozens of tiny. Fifty years later, it's still a thrill to create a diamond, a thrill we tried to capture in a story in the June issue of Smithsonian magazine. One of the barriers to publishing a story about diamond growers is that almost everyone involved is touchy about secrecy.

His solution was to invent another apparatus, called the tetrahedral press, that was even better and that circumvented all the patents held by GE. Germany United States. Times has the best obituary of Hall that I've seen. Tracy Hall was the first guy to turn carbon into diamonds.
A chemist who worked for General Electric, he and his colleagues somehow created a method that resulted in synthetic diamonds that were, by all accounts, exact duplicates of the real thing. Being a very intelligent man, he recognized this as a terrible insult, so he left the company and found another way to create synthetic diamonds for which he would hold the copyright.

Hall had his share of secrecy worries as well. Previous Slide Next Slide. Hazen Hall's success, in his telling of the story, came about because of his determination to go his own way with a radical redesign of the press, which employed a doughnut-shaped die surrounded by shrink-fit steel sleeves the belt which confined the sample chamber and two curved and tapered pistons which pressed on the sample chamber. The first successful reproducible experiment was completed on the morning of December 16, by Hall in his unique "Belt" apparatus. Professor Hall's main research interests are in software engineering.
