Advanced Porous Ceramics - Refractron Technologies Corp
Refractron Technologies Corp. manufactures porous alumina (brown and white fused grits), silica, desiccant and mullite ceramics with precisely controlled porosity. Our tubes, air stones, discs, domes, and plates function as fine bubble diffusers that oxygenate, purify, and filter water in numerous applications. They also transfer gases to liquids under controlled flow for fish farms, aquatic plants, beverages, and aquariums. In addition, saturating the porosity of these materials with ink produces fingerprint touch surfaces.
