In a cohort study (Edling, 1987; see chapter 7.10.2) more than 500 individuals exposed to silicon carbide working in the manufacture of abrasives were followed up from 1958 until 1983. The study revealed no significant increase in total mortality, cancer mortality, or incidence of non-malignant respiratory diseases ascribable to silicon carbide.
SILICON CARBIDE PRODUCED NO FIBROSIS OF LUNGS IN NORMAL EXPERIMENTAL ANIMALS, BUT PROFOUNDLY ALTERED THE COURSE OF INHALATION TUBERCULOSIS, LEADING TO EXTENSIVE FIBROSIS & PROGRESSIVE DISEASE. INERT REACTION RESULTED WHEN SILICON CARBIDE WAS INJECTED IP IN GUINEA PIGS.

Its primary use is in optics for aerospace and defense, and it is therefore considered a strategic material controlled by the National Defense Stockpile. Long lead times for beryllium scanner mirrors are common. Silicon carbide can replace beryllium in high-speed
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
Leading with rich International experience, ITK utilises the skills to manufacture various grades of Silicon Carbide which are extraordinarily hard, wear-resistant and possess excellent thermal conductivity properties. Silicon Carbide is a new type of engineering
1/1/1991· Silicon carbide (SiC) was first prepared in laboratory experiments in the first half of the nineteenth century. Acheson was one of the first to realize the importance of the carbide as a grinding and cutting material and, by 1892, had devised a process for its commercial
A factory to manufacture silicon carbide is planned to be set up at Jubail Industrial Park by a three-sided international joint venture. Silicon carbide venture planned of Japan announced yesterday that they have signed a "memorandum of understanding" (MoU) under which they will form a joint venture to construct and operate a new plant for manufacturing silicon carbide in Saudi Arabia.
Silicon Carbide has been developed to meet a high quality technical grade ceramic with excellent mechanical properties. It is highly wear acids resistant and also showing very high heat resistance, this material is widely used in abrasives, refractories and kiln furniture in extreme conditions.
In the manufacture of silicon carbide resistors, the steps comprising providing a current carrying path adjacent and around the resistor and having a specific resistance of predetermined relationship to that of the resistor to be cured therein and passing a heating
Silicon Carbide - this easy to manufacture compound of silicon and carbon is said to be THE emerging material for appliions in electronics. High thermal conductivity, high electric field breakdown strength and high maximum current density make it most promising for high-powered semiconductor devices.

Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in appliions requiring
