INTERNALLY-HEATED HIGH-PRESSURE APPARATUS FOR SOLVOTHERMAL CRYSTAL GROWTH - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240026562 titled 'INTERNALLY-HEATED HIGH-PRESSURE APPARATUS FOR SOLVOTHERMAL CRYSTAL GROWTH

Simplified Explanation

The disclosed invention is an apparatus for solvothermal crystal growth. It consists of a cylindrical enclosure, a cylindrical heater, a first end closure member, a load-bearing annular insulating member, and a first end plug. The cylindrical heater has a cylindrical wall that defines a capsule region and is equipped with a first end and a second end. The first end closure member provides axial support for a capsule placed within the capsule region. The load-bearing annular insulating member is positioned between the cylindrical enclosure and the cylindrical wall of the heater. The first end plug is located between the first end of the cylindrical heater and the first end closure. The load-bearing annular insulating member or the first end plug is made of a packed-bed ceramic composition, which has a density ranging from about 30% to about 98% of the theoretical density of a 100% dense ceramic with the same composition.

  • The invention is an apparatus designed for solvothermal crystal growth.
  • It includes a cylindrical enclosure, a cylindrical heater, a first end closure member, a load-bearing annular insulating member, and a first end plug.
  • The cylindrical heater has a cylindrical wall that creates a capsule region for crystal growth.
  • The first end closure member supports the capsule within the capsule region.
  • The load-bearing annular insulating member is placed between the cylindrical enclosure and the cylindrical wall of the heater.
  • The first end plug is positioned between the first end of the cylindrical heater and the first end closure.
  • The load-bearing annular insulating member or the first end plug is made of a packed-bed ceramic composition.
  • The packed-bed ceramic composition has a density between about 30% and about 98% of the theoretical density of a 100% dense ceramic with the same composition.
