Silicon-carbide can be found in block-knife sharpeners, but I found they were too expensive. Instead, I used a silicone-carbide rubbing stone for under $14 found at the hardware store. The crucible I used was metal with a higher melting point that the melting I was attempting to smelt.
The Ins And Outs Of Silicon Carbide
You can make a MOSFET in silicon and you can make a MOSFET in silicon carbide. MOSFETs in silicon are very common in the low-voltage region, from 10 volts up to about 300 volts. Above 300 volts, the resistance of a silicon MOSFET gets very very high and it makes the MOSFET unattractive.

Gallium Oxide Could Have Low Cost in Future, NREL …
The NREL analysis determined it would cost $283 to manufacturer a six-inch gallium oxide wafer in the United States, less than a third of the $919 it would cost to make a silicon carbide wafer. The significantly lower wafer cost enables the gallium oxide containing power electronics (that also are comprised of numerous other components and packaging) to be twice as cheap.
Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
With silicon carbide ceramics the material properties remain constant up to temperatures above 1,400 C. The high Young’s modulus > 400 GPa ensures excellent dimensional stability. These material properties make silicon carbide predestined for use as a

Making reusable reaction‐bonded silicon nitride …
Moreover because silicon sticks with the quartz crucible during solidifiion, the crucible needs to be spray coated with silicon nitride powders, about 1 μm in size, as a releasing agent. Although the commercial nitride powder is purer than the quartz crucible, its metallic contents are still in the level of several ppmw; boron and phosphorus are at least 1 ppmw or higher.

silin carbide abrasive
Silicon Carbide has a lower hardness and abrasive capacity than industrial diamond and boron carbide. Yet because of its much lower cost when compared with diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts.
Silicon Carbide - Casting Material | Wanhua Metal
Silicon carbide products manufacturing process: The common method is to mix quartz sand with coke, use the silica and petroleum coke, add wood chips, put it into an electric furnace, heat it to a high temperature of about 2000 C, and obtain silicon carbide after
Initially I didn''t put the second weld on my first crucible and somehow the single weld split. Now I spend the extra time on all of them I make. Since I was in the crucible making and reparing mood I decided to alter my big old standby crucible.
