Ultra-Pure Silica at Scale
3N 99.9% SiO₂ -> 5N 99.999% SiO₂ advanced silica material production for high-value markets within the renewable energy transition
Why Our Silica is Different
Three key advantages that set us apart in the high-purity silica market
Exceptional In-Situ Purity
Santa Maria Eterna sand averages >99.6% SiO₂ even before any processing, providing a superior starting point for purification.
Low Impurity Suite
Iron below 7 ppm and Aluminum under 9 ppm after simple washing process allowing rapid upgrade potential that significantly reduces operational expenses.
District Control
Fully permitted homogenous HPQ assets under 40-year leases ensures multi-decade feedstock security and supply chain control.

Environmental Advantage - Non-HF Processing
Homerun’s Belmonte Project silica can be successfully purified without hydrofluoric acid (HF), one of the most hazardous industrial chemicals. Traditional high-purity quartz processing relies heavily on HF, which poses:
Severe environmental risks
Extreme worker safety hazards
Regulatory permitting challenges
High insurance and liability costs
1
Raw Material
99.6% SiO₂ sand input
2
Thermal Treatment
Hydrofluoric acid free purification
3
Final Product
3N – > 99.9% SiO₂ output
Homerun's validation of phosphoric acid baking, caustic baking, and with further chemical and thermal treatment pathways provides multiple environmentally superior processing options. This differentiates the Belmonte Project from competing silica projects that require HF treatment to achieve comparable purity levels.

CEITEC: Substrates and Wafers
Establishing Technical and Institutional Collaboration to Build and Qualify Advanced SiC Semiconductor Substrates and Wafers, Fostering a Complete Brazilian Supply Chain
Homerun's MOU with CEITEC
Homerun announced that it has executed a MOU with CEITEC, a state-owned semiconductor company headquartered in Porto Alegre, Rio Grande do Sul, Brazil.
This strategic agreement establishes general guidelines for technical and institutional cooperation between the two organizations, focusing on the joint development of studies, projects, and activities in the field of silicon carbide (SiC) substrate and wafer technologies.
The cooperation aims to develop, produce, qualify, and establish manufacturing capabilities for semiconductor-grade SiC substrates and wafers produced by Homerun for offtake by CEITEC to foster a complete, vertically integrated local supply chain within Brazil.
CEITEC Roles and Responsibilities
To operationalize this initiative, technical teams from both organizations will collaborate under structured Work Plans.
Provide highly precise technical requirements and specifications for SiC substrates and wafers suitable for semiconductor applications.
Support the technical development and physical validation of SiC semiconductor devices utilizing qualified substrates and wafers, offering direct engineering feedback for material and processing improvement.
Contribute its advanced semiconductor manufacturing expertise and identify technological requirements, resource gaps, and potential strategic partners to construct a complete SiC value chain in Brazil.
