Abstract
A method of forming a dissolvable part of amorphous borate includes: preparing a mixture comprising one or more boron compounds and one or more alkali compounds, at least one of the one or more boron compounds and the one or more alkali compounds being hydrous; heating the mixture to a melting temperature for a predetermined time to melt the mixture and release water from the mixture to form an anhydrous boron compound that is moldable, wherein the amount of alkali compound being selected to achieve an alkali oxide content of between about 10 to 25%; with the anhydrous boron compound at a molding temperature, molding the anhydrous boron compound in a mold; and cooling the anhydrous boron compound to form a solid.
Claims16
A method of forming a dissolvable part of amorphous borate, the method comprising the steps of:
- preparing a mixture comprising one or more boron compounds and one or more alkali compounds, wherein at least one of the compounds is a hydrous compound;
- heating the mixture to a melting temperature of between about 700° C. and about 1000° C. and dwelling at the melting temperature for a sufficient time to release the water in the mixture and form an anhydrous boron compound that is a moldable fluid, wherein the amount of alkali compound selected achieves an alkali oxide content in the moldable fluid of between about 10 mol % to 25 mol %;
- molding the anhydrous boron compound in a mold;
- and
- cooling the anhydrous boron compound to form a solid to below a strain point of the solid over a period of at least 1 hour.
