Abstract
The present invention employs poly(ethyloxazoline) as a temporary binder and lubricant during the preparation of greenware articles. According to the present invention, molten poly(ethyloxazoline) promotes the compressibility of the powder used to form the greenware article, thus improving the density and strength of both the greenware and the abrasive article. The molten poly(ethyloxazoline) acts as a lubricant to permit a more efficient grain rearrangement under applied pressure and thereby increases the average density of the greenware article by 6 to 8 percent as compared to standard cold pressing.
